Description

The Optronics STL37RB is a left-side LED combination taillight designed for trailers over 80 inches wide. It features 23 diodes for bright, efficient illumination across stop, turn, tail, side marker, side reflex reflector, rear clearance, rear reflex reflector, and license plate functions. The light is fully waterproof and submersible, constructed with a sealed plastic housing and acrylic lens to protect the internal circuit board from corrosion and short circuits.

This taillight is DOT compliant and PC rated for a 180-degree beam pattern, ensuring visibility from multiple angles. Installation is simplified with a surface-mount design and a 3-wire pigtail for easy connection, with brown for tail lights, yellow for stop/turn signals, and white for ground. It operates on 12V and has a low amp draw of 0.181A for stop/turn and 0.047A for the marker light.
