Truck-Lite has developed what it calls the "first ever" LED perimeter lamp, providing brightness where there normally isn’t much at all because traditional dome lamps won’t reach either side- or rear-door liftgate areas of a truck or trailer. The safety bonus using this white-light LED is quite real.

When mounted at an ideal height, Truck-Lite’s perimeter lamp directs about 20 sq ft of illumination, attributed to "innovative mounting and optical design," says the company.

Truck-Lite says the new lamp is a robust piece of work, and using just 4 diodes it delivers 365 lumens of light output. Constructed of a heavy-duty, corrosion-resistant, die-cast aluminum housing, the low profile lamp’s design protrudes only 2.5 in. from the vehicle surface. The lens is made of impact-resistant polycarbonate and rear fins keep heat away from the LEDs and lamp circuitry, allowing for increased light output and lamp longevity.
