Truck-Lite’s LED Perimeter Lamp installs at the back of the trailer to illuminate dark areas that regular dome lamps do not reach. It helps light loading and unloading areas to create a safer environment for truckers. It is housed in corrosion-resistant, die-cast aluminum, and it uses four diodes for a resulting output of 365 lumens that reach an area of 20 square feet. The light juts out only 2.5 in. from the trailer. Truck-Lite, truck-lite.com
