Truck-Lite 29002R 21 Series Red Rectangular Incandescent Marker Clearance Light Kit | 2-Bulb, .180 Bullet & Ring Terminal, 12V

Ensure total rear-profile compliance and maximum highway safety with the Truck-Lite 29002R 21 Series Red Rectangular Incandescent Marker Clearance Light Kit. Designed as an all-in-one installation package, this heavy-duty 1" x 4" class clearance lamp setup is an industry standard for commercial semi-trucks, fleet trailers, and utility bodies. The kit includes a high-visibility red 2-bulb sealed lamp, a rugged 2-screw surface mount branch/bracket assembly, and a matching plug-in wiring harness for a complete lighting overhaul.

Dual-Bulb Reliability & Sealed Defense

Never worry about a single blown filament leaving your truck unlit on dark highways. The Truck-Lite 29002R utilizes an advanced 2-bulb configuration, meaning if one filament fails, the secondary bulb continues to illuminate, keeping your vehicle safe and legal until maintenance can be performed. To protect against the punishing elements of commercial transport, the high-impact polycarbonate lens and housing are sonically sealed together, forming an impenetrable, one-piece barrier that keeps out moisture, road grime, salt spray, and dust.

Heavy-Duty Bracket & Harness Integration

The 29002R installation kit removes the guesswork from rewiring. It features a heavy-duty, impact-resistant black polycarbonate mounting bracket that secures tightly using a standard 2-screw setup. Electrical connections are rock-solid thanks to the male pin lamp design paired with a specialized .180 bullet terminal and ground ring terminal harness. This configuration allows for rapid, plug-and-play servicing while maintaining a highly secure seal against road vibration and terminal oxidation.
