The Optronics International Corner-Mount Interior LED Lamp, No. ILL38CMB, is a modular, low-profile lamp designed to be installed in any trailer as original equipment or as an aftermarket upgrade. The light relocates a vehicle's critical interior lighting sources away from the high-traffic central core of a vehicle where they are vulnerable to potential harm, and reorients them to the corners of a vehicle's ceiling. It has a modular design that enables multiple LED lamps to be spaced along the ceiling of a vehicle or configured as two continuous bars of light on ceiling corners throughout the entire length of a vehicle. The lamps have a sturdy corner-mount design that attaches securely to both the ceiling and the wall. This light is compatible with both 12V and 24V electrical systems, operates in both refrigerated and non-climate-controlled environments, and has an operational range of -4 degrees F to 140 degrees F.
