Truck-Lite 29202Y 21 Series Yellow Rectangular Incandescent Marker Clearance Light | 2-Bulb, Male Pin Connector, 12V

Maintain maximum vehicle side-profile visibility and full DOT compliance with the Truck-Lite 29202Y 21 Series Yellow Rectangular Incandescent Marker Clearance Light. Widely trusted as an industry standard for commercial semi-trucks, dry van trailers, flatbeds, and vocational vehicles, this 2" x 6" class marker lamp provides heavy-duty dependability. Built with dual-bulb redundancy and a sonically sealed housing, this individual amber replacement lamp is engineered to handle the everyday punishments of long-haul transport.

Dual-Bulb Safety Redundancy & Weatherproof Seal

Eliminate the risk of immediate roadside citations or dangerous blind spots due to a single burnt filament. The Truck-Lite 29202Y is intelligently engineered with an advanced 2-bulb configuration. If one filament breaks due to extreme chassis vibration, the secondary bulb remains actively illuminated—keeping your vehicle safe, visible, and legal until your next scheduled maintenance stop. To defend against heavy road spray, dust, and corrosive winter chemicals, the high-impact polycarbonate lens and housing are sonically sealed together to create an absolute one-piece barrier against moisture intrusion.

Secure Male Pin Terminal Interface

Say goodbye to intermittent electrical shorts caused by loose, corroded connections. This 21 Series lamp features a heavy-duty 2-prong male pin connector design (compatible with industry-standard PL-10 right-angle plug harnesses). The integrated male pins lock securely into place to resist backing out under continuous road shock. Designed for a standard 2-screw surface mount configuration, it seamlessly retrofits onto existing vehicle brackets or body panels with minimum effort.
