Optronics ST57RS Submersible Rectangular Trailer Tail Light - Driver Side - 8 Function - Incandescent

The Optronics ST57RS is a submersible rectangular combination tail light designed specifically for the driver side of trailers over 80 inches wide. This waterproof incandescent light assembly features a red lens and serves eight critical functions to ensure complete lighting compliance and safety.

Key Features:

• 8-function design: brake, tail, turn signal, side marker, side reflector, rear clearance, rear reflector, and license plate illumination
• Submersible waterproof construction ideal for boat trailers and applications where the light may be submerged
• Measures 6-1/16 inches long x 3-3/4 inches tall x 2-1/4 inches deep
• Stud mount installation on 2-inch centers for secure attachment
• 3-wire design with yellow wire for driver side stop/turn function
• Incandescent bulb technology for reliable performance
• Designed for trailers over 80 inches wide requiring rear clearance lighting

This combination tail light is engineered with sealed, waterproof construction that makes it perfect for marine trailer applications where the light assembly will be repeatedly submerged during boat launching and retrieval. The driver side configuration includes integrated license plate illumination, eliminating the need for a separate license plate light. For passenger side applications, the corresponding model is ST56RS.
