CAN REFLECTIVE MATERIAL BE USED ON A SIGN TO MAKE IT LIGHT UP?
No, reflective material only works when you are behind the point of light, in example a pair of headlights. Putting reflective material on a sign that is 6 feet off the ground or more will not light up at all – typically headlights don’t reach that high. Using reflective material on a truck side is a different story – it will light up from a distance as it passes in front of other vehicles at an intersection.
