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

Ensure maximum side profile visibility and legal fleet compliance with the Truck-Lite 29002Y 21 Series Yellow Rectangular Incandescent Marker Clearance Light Kit. Designed as a comprehensive, plug-and-play installation package, this heavy-duty 2" x 6" class clearance lamp setup is an industry favorite for commercial semi-trucks, dry van trailers, flatbeds, and vocations vehicles. The kit comes fully equipped with a high-visibility amber/yellow 2-bulb sealed lamp, a rugged 2-screw surface mounting base, and a dedicated plug-in harness for an efficient lighting overhaul.

Dual-Bulb Redundancy & Sonically Sealed Defense

Eliminate the risk of roadside citations caused by single blown filaments. The Truck-Lite 29002Y is engineered with an advanced 2-bulb configuration, guaranteeing that if one filament breaks due to extreme road shock, the secondary bulb continues to illuminate to keep your rig safe and compliant until your next service stop. To handle the brutal spray, wind, and debris of long-haul transport, the high-impact polycarbonate lens and housing are sonically sealed together, creating a watertight, one-piece assembly that eliminates internal lens fogging and moisture intrusion.

Secure Male Pin & Harness Integration

The 29002Y kit eliminates intermittent power failures caused by loose, corroded connections. The lamp features a robust male pin socket design that locks securely into the included PL-10 type plug connection. Electrical routing is cleanly finalized via a heavy-duty, 18-gauge wiring harness outfitted with a .180 bullet terminal and a pre-attached ground ring terminal. This provides a reliable isolated ground circuit, making it ideal for non-metallic mounting environments like fiberglass cabs, sleeper boxes, or painted utility bodies.
