Best Color Reflective Tape for Day and Night Visibility

Best Reflective Tape Colors for Reducing Accidents Involving Vehicles (online store –

Accidents involving vehicles are one of the leading causes of death due to injury in the United States and around the world. In most cases, these accidents are the unfortunate result of one driver not seeing another automobile, pedestrian, bike rider or motorcyclist in time to stop or avoid hitting them. Simply put, increasing visibility day and night increases reaction time which in turn substantially reduces the number of injuries and fatalities. Brightly colored reflective tape is the main method of increasing visibility day and night.

There are two choices when selecting a reflective tape, glass bead or prismatic.  Roadway applications require a tape that can be seen from long distances and prismatic reflective tapes in bright colors can be seen much farther than standard glass bead reflective tapes. (Thousands of feet instead of hundreds.) The colors below represent the most visible day and night.

  • V98 Prismatic Fluorescent Lime (Great by itself or combined with other colors. Shows up well against darker backgrounds.)
  • V98 Prismatic Fluorescent Orange (Great by itself or combined with other colors. Shows up well against lighter colors.)
  • Prismatic Red (Good when combined with a lighter color like yellow or white.)
  • Prismatic Standard Yellow (Good when combined with a darker color like red or orange.)
  • Prismatic Standard Orange (Good when combined with a lighter color like yellow or white.)
  • Prismatic Standard Blue (Good combined with a lighter color.)

(Prismatic red is available in V82, V92 or V98. Prismatic standard yellow is available in our V82 product line.  Prismatic standard orange is available in our V92 and our V82 line.)

These colors can be combined to create contrasting areas of reflective tape or used alone. Combining colors can greatly increase the visibility of a vehicle. A battenburg or chevron panel is very effective.

If you choose to use a single color a Fluorescent Lime is recommended on a darker background and a Fluorescent Orange is recommended on a lighter background. I prefer the Reflexite V98 conformable prismatic over all other tapes because of its flexibility, durability and brightness.

Reflexite V98, V92 and V97 prismatic reflective films by Orafol are very similar in appearance but have some distinct differences.  Each have specific characteristics that make it most suitable for certain conditions.  The one you select will depend on your application.  To summarize you would use a V92 film when striping flat areas where high initial tack is needed.  You would use V98 where conformability is needed to go over complex curves.


Reflexite V92 prismatic and V98 prismatic tape are about the same brightness. The chart below shows the reflectivity in candelas for the V92 and the V98 is going to be about same or slightly higher.  Note that the chart below shows minimum values.  Actual reflectivity is normally about 35 – 40% higher than the chart.

Both tapes are very bright and can be seen from over a thousand feet away in many applications.


Reflexite V98 and V92 tapes are both metalized polyester films. The V92 film is thin and flexible while the V98 film is engineered to be “conformable” as well as flexible.  Conformable simply means that the film will stretch or give a little.  V92 films are fine for flat surfaces or surfaces without compound curves.  V98 films are designed to perform on flat surfaces as well as surfaces with compound curves.

It is important to note that when you install the V98 material you do not want to stretch it like a rubberband and install it.  If you do it will pull back to its original shape.  To take advantage of the V98 materials conformability you would apply it to a surface, warm it with a hair dryer and mold it to compound curves using a soft cloth.

V98 conformability moldable


V92 and V98 films utilize two different types of adhesive.  V92 adhesive grabs immediately and does not want to let go.  It is very strong making the tape great for applications where a high initial tack is needed.  The V98 film uses a repositionable adhesive meaning it is less tacky initially and allows the installer to pull it off an reapply if necessary.  The V98 films gain adhesion over time.  If removal at a later date is necessary, the V98 will come off easier and leave a cleaner surface.

Orafol-Reflexite V92 is less expensive than V98.  If you want a bright and tough yet affordable tape then V92 is the solution.  The V98 is more expensive but if you need a conformable product that is brighter then it is the way to go.


Orafol-Reflexite V92 film is very thin.  About .008 of an inch thick.  This is about like a couple of sheets of paper.  For certain applications a thin film is desirable.  V98 is about twice as thick.  This is still very thin but it is thicker than V92.  Reflexite invented prismatic tape and they make it in a single patented layer which is why it is thinner than the competition.  The single layer design also means that V92 and V98 tapes will not delaminate like other films.

Color Comparison

V92 and V98 films look almost identical.  For some colors a slight difference can be seen.

Note – The V98 Orange that we carry is a Fluorescent Orange.  Our V92 Orange is a standard Orange.  That is why the two colors look different.

Reducing Rear End Collisions – Reflective Tape for Work Vehicles (Part 1)

Reducing Rear End Collisions and Accidents Involving Commercial Vehicles through the use of High Visibility Reflective Materials – Part 1

Each year in the US there are approximately 5.5 million automobile accidents resulting in over 30,000 fatalities.  About 1/3 of these accidents involve rear end collisions. Rear end collisions occur when a driver does not see a slower or stopped vehicle in front of them in time to stop.

The US Department of Transportation reports that there approximately 400,000 accidents involving “large trucks” (GVWR > 10,000 lbs) each year.  5,000 of these accidents result in fatalities, 109,000 result in some type of bodily injury and all resulted in property damage.  Out of these accidents, rear end collisions result in a higher percentage of injuries, fatalities and property damage. Keep in mind that these number are just for large trucks.

Another fact to consider is that about 50% of fatalities occur in the day and about 50% occur at night indicating that day and night time visibility are equally important.

Commercial businesses with fleets of vehicles, Utility Companies, Police Departments and Emergency Service Organizations all have to deal with the cost and liability of highway accidents involving their vehicles.  These types of vehicles are at higher risk because of their tendency to stop near moving traffic.  As you drive each day you will no doubt come across vehicles that you have to slow down and avoid.  These would be ambulances, school buses, fire trucks, police cars, utility trucks, cable company vehicles, delivery trucks, gas company trucks, oil and fuel trucks, snow plows, garbage trucks and other such vehicles.  Seeing these vehicles early can prevent a collision.

Consider this example. Everyone is familiar with the brown UPS delivery vehicles.  They are everywhere.  Lets say that it is getting dark and you round a curve at 30 mph and there before you is a large brown ups van parked in the road. Since the van is brown it blends in very well with the dark night.  What is it that keeps you from hitting the UPS vehicle?  Now lets say you round the same corner and see the same truck but with bright yellow and red alternating stripes marking the rear of the vehicle.  You will now see that vehicle and be able to slow down in time to avoid a collision. The point is, visibility is important.

When tasked with making a fleet of vehicles more visible day and night, there are several factors to consider.  These are –

The colors of the material to be used.
The Intensity or brightness if Reflective material is used.
The Configuration of the tape or panel. (Chevron,Non Slanting,Message, etc..)
The Placement of the material on the vehicle. (location – rear, sides, front)

Selecting the Right Color and Intensity Reflective Material to Make a Vehicle more Visible

If you have been researching making a vehicle more visible you have no doubt come across the word “conspicuity”.  As in conspicuity tape or conspicuity treatment.  Conspicuity is defined as the characteristics of an object influencing the probability that it will be detected by coming to the attention of an observer.  In other words, it is how easily something can be seen.  For example, a bright yellow Ferrari is more conspicuous than a black one.

When marking commercial vehicles the goal is to make them more visible or conspicuous to the human eye. Color and luminance contrast are two factors that affect conspicuity.  These factors are often what trigger recognition of an object.

The average human has an approximate 130 degree field of vision. Our central field of vision is where we see detail. Our central vision field makes up only 5% of the 130 degree field. Our periphery vision makes up the rest. Color alone is not sufficient to locate or distinguish objects in our peripheral field of vision.  To detect objects in this area we need contrast and luminance as well as color.

Luminescence Contrast

Luminescence is defined as the summed emission of visible light by an object, substance or material.  In other words it is how bright or vivid something is.  In this case we are interested in the visible light reflected from a surface to the human eye. The luminance of object depends on how much light strikes and object and how much is reflected.  (Some materials reflect more light than others.)  Luminance contrast is simply the difference in the brightness of two colors whether it be two colors side by side or one color in front of a dark or bright background.

The human eye distinguishes color and luminance through two types of photoreceptor cells. Cones and rods.  Cones are more concentrated at the center of the eye while rods are more towards the outside or periphery.  Cones distinguish color and detail.   Rods are more sensitive to changes in luminance or movement.  Rods require less light to function and are more efficient at night.  Cones give us our central vision (color and detail)  Rods give us our peripheral vision. 

As you read this article, it is the cones in your eye that allow you to see the detail and contrast which is what allows you to see and read the words.  As you focus on the words you will notice that you are also taking information in from your peripheral vision. This information is coming from the rods in your eye. If while you are reading this sentence, something moves in your periphery, you will notice it.  Also, if there is a bright color that is out of the ordinary, you may see that as well. Try this.  Click on the yellow and red picture above to make is larger.   After you click on the image look 30 – 45 degrees to the right or left and focus on something besides the screen of your computer.  Notice how in your periphery vision you can still see the bright yellow and red graphic.

In the daytime, the color of an object determines how bright or luminous it is.  At night, with reflective sheeting, color and type both play a role in how visible the sheeting is. By type I mean the brightness of the reflective tape. (type 1, 2, 3, 5, 8)  For example, a prismatic reflective material (type 5 or above) will be about 5 times brighter than a standard engineer grade (type 1) material.  So at night, both color and type affect visibility.  Because of this, we recommend a prismatic tape over the less intense tapes.


Color is determined by which wave lengths of light are reflected back to the human eye.  The wavelengths or combinations of wavelengths give us what we know as color or hue. Colors such as Fluorescent Lime/Yellow and Fluorescent Orange are considered to be the most conspicuous colors during the day and in low light conditions.

 Definition of Fluorescent – the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence.  Fluorescence makes a color look as if it is glowing.

They are more conspicuous in both the primary and periphery field of vision. The main fluorescent colors are lime/yellow and orange.  Fluorescent lime is commonly seen in school zones and fluorescent orange is seen in work zones. Fluorescent colors are especially visible at twilight or dawn when the ultraviolet light from the sun is present in great proportions than in full sunlight.

Standard Red, Orange and Yellow are also conspicuous colors.  Red and Orange are useful as contrasting colors with  fluorescent lime or yellow being the alternating color.


Brightness or Luminance is important but contrast is also needed for objects to be conspicuous.  If you sheeted the back of a truck with just fluorescent lime or standard yellow material you would certainly make it more noticeable.  However, by adding a contrasting color such as red or orange you greatly increase the trucks visibility in both the periphery and primary fields of vision.

Red is often used with fluorescent lime yellow as a contrast color and is very effective.  The most visible reflective panels would be red and fluorescent lime/yellow or orange and fluorescent lime/yellow.  It is difficult to say which is the most visible.  I would lean a little towards the lime/red because of the contrast. The picture below shows the three colors.

Fluorescent lime and red will give you a 3 to 1 contrast ratio.

Fluorescent lime and fluorescent orange will give you a 2 to 1 contrast ratio.

Fluorescent lime and standard orange will give you an approximate 2.5 to 1 ratio.

Reflective Fluorescent Lime and Orange. Along with Reflective Red.


For maximum visibility we recommend you use a fluorescent lime/yellow material and a red or fluorescent orange or standard orange contrasting material.  The chevron pattern is recommended but an alternating non slanting pattern is also effective.  A chevron pattern slants down and out at 45 degree angles which is normally going to be different from other lines on a vehicle and therefore more conspicuous.  However, there is no research that I know of that shows the chevron pattern to be superior to a simple alternating pattern.  The main considerations are the brightness of the tape and the contrast.

Reducing Collisions Involving Commercial, Utility and Work Vehicles by Using Reflective High Visibility Panels

Studies in the US and overseas show that by using high visibility reflective sheeting, accidents can be reduced by as much as 41% on the high side and 15% on the low side.  The differences in effectiveness are going to be affected somewhat by the brightness, color,contrast, size, type and placement of the reflective treatment or panels.  These numbers apply to both rear end and side collisions.

In previous articles we have discussed the science of visibility or conspicuity and how to use high visibility reflective tapes or panels to reduce rear end collisions. We also discussed the most visible colors to use.  In this article I want to cover the  type  (design), size and placement of the reflective treatment so that the maximum benefit is achieved. In other words, what should your panels look like, how big should they be, and where should you place them?

Type of Reflective Panel to Use (Design)

There are several panel designs and color schemes that can be used to mark the rear, sides and fronts of vehicles to make them more visible.  As we discussed in part 2 of this series, a fluorescent lime yellow and either red or orange is a good choice for color combinations in that they provide contrast and are bright colors by themselves. The picture below shows the different configurations that panels can be made in.  There may be more but these are the main ones.

All three of the panels styles above will grab an observers attention.  The one with the words has the advantage of conveying a message at the same time. The bottom two are basic alternating color panels.  The middle is a non slanting design and the bottom is a slanting design also called a chevron pattern.  People choose the different designs for different reasons.  The chevron is chosen because it is unique and is often more conspicuous, however, since it is used on fire trucks it is often associated with that application.  Therefore, many companies or organizations will opt for the middle pattern or the message panel to differentiate their vehicles from fire trucks.

Reflective Panel Size

The NFPA (National Fire Protection Association) recommends that 50% of the rear of a fire truck be covered with reflective material in the form of a chevron pattern.  The minimum reflectivity would be a type 1 or engineer grade.  Also, any yellow or red is acceptable.

By using a highly visible prismatic material and using a fluorescent color a panels visibility factor increases substantially.  For example, a prismatic fluorescent lime yellow reflects at a rate of 420 candelas.  A standard yellow engineer grade reflects at about 70 candelas.  This makes the prismatic fluorescent 6 times more reflective at night.  Other research shows that the fluorescent lime/yellow is at least twice as visible in the daytime. It is felt that smaller, bright prismatic panels can do the job of much larger less reflective panels.  It is recommended that you use prismatic grade material especially if you want to cover only a small portion of a vehicle.  For non regulated vehicles the general rule is that you want to cover enough of the sides or rear of the vehicle to make it conspicuous without going overboard and creating a distraction.  The picture below shows the different sizes and configurations that reflective panels come in.

Reflective Panel Placement on the Vehicle

The last consideration is where to place the panels to gain maximum visibility and effectiveness.  The rear of the vehicle would be the first area to consider followed by the sides.  A stopped vehicle is most likely to get hit from the rear, however, side impacts for commercial vehicles are also common.  Panels should be placed as low as possible or near the same level as the hood of a typical passenger car.  Since panels are retro reflective and reflect light back to the light source, placing them too high can impede reflectivity.  If you pull up behind a large truck at night you will notice that as you get closer, the lower reflective tapes still reflect and the higher ones begin to dull out.   Just remember that light has to hit the tape from a cars head lights and then bounce back to the drivers eyes.  If you have a panel on the upper portion of a van then the headlights will not even be close to hitting that panel as the vehicle gets close. From far out it will not matter as much but at closer distances it will.  The picture in the chart below shows how this works.

When marking your vehicle or trailer with reflective tape, sheeting or panels, it is important to select the right color combination. Color, contrast and brightness are all important and can make the difference between being seen and not seen day or night.  The color you select should “contrast” with the other colors it is up against.  This makes it conspicuous which is the goal.  The tape color should also be “bright” so it can be seen from as far away as possible. The tape “type” should also be as bright as possible.  (example – type 1 bright, type 3 brighter, type 5 even brighter, and so on)

Studies show that bright fluorescent lime yellow is the brightest and most conspicuous color. This is true day and night.  The image above is an example of how bright fluorescent lime is.  Notice the nice contrast that you get with the red. (both colors are reflective)

Note – With that being said let me just mention that white is brighter but it does not stand out as a conspicuous color.  It tends to blend in with white backgrounds, car headlights, street lights, the moon, etc..

Fluorescent Lime is a very unique color and is not common in what we see day to day or at night.   Fluorescent Orange is also like this.  Both of these colors get peoples attention because they are unusual and bright.  Of these two colors the brightest would be the lime. The image above shows fluorescent lime and orange panels.  Notice that you still have nice contrast and both colors are very bright at night.

As an offsetting color for fluorescent lime you would want to select a red, a fluorescent orange or a standard orange.  By alternating these colors you would provide the highest contrast using the most conspicuous colors.   This makes you visible and safe both day and night.

In summary, to be seen day and night use red and fluorescent lime reflective material or orange and fluorescent lime material.  When placing the panels on a yellow or red vehicle you can change the lime to a white and then use orange or red as the offset.
