Horizontal Chevron Panels with 4″ Stripes – Online Store
Horizontal Bi-directional Chevron Panels are generally used on the rear of a vehicle either on the tailgate or bumper. They are highly visible but not so large as to be considered unsightly. They also provide extra visibility at an affordable price. Great for fleet applications. 
This type of panel is used for non NFPA applications. That simply means that they can be used for every application except fire trucks which require a 6″ stripe. The narrower 4″ stripe results in more alternating stripes per foot which for certain applications is preferable.
As you can see from the image above, the panels are available in several widths and length combinations. You can also get the panels in orange and fluorescent lime, red and white and orange and white. The white and orange and white and red panels are effective on vehicles that are yellow or tan where a lime may blend in too much. Overall, red and fluorescent lime or orange and fluorescent lime are the most visible and most popular. The picture below shows the orange over white and fluorescent lime.
It is recommended that these panels be placed low on the rear of the vehicle. At about the level of an automobiles headlights. They perform best when installed this way. 
All of our panels can be trimmed with scissors or an exacto to fit. The material is rugged, however, it is also pliable and cuts very smoothly.

It is important to keep in mind that although white is brighter than fluorescent lime, it is not necessarily more conspicuous. White tends to blend in with other white lights such as car headlights, street lights, etc.. Also, the contrasting color, orange or red, needs to be less reflective to provide the necessary contrast. A 2 or 3 to 1 contrast is recommended.
