Truck-Lite 29204C 21 Series Clear Rectangular 2-Bulb Incandescent License Plate Light | 2-Screw Mount, Male Pin Connector, 12V
Ensure crisp, reliable nighttime license plate visibility and complete DOT regulatory compliance with the Truck-Lite 29204C 21 Series Clear Rectangular Incandescent License Plate Light. Widely trusted as the standard commercial footprint for semi-trucks, fleet trailers, vocational vehicles, and specialty equipment, this 2" x 6" class license lamp provides heavy-duty performance. Built with a twin-bulb backup configuration, a shock-absorbing assembly, and a sonically sealed clear housing, this individual replacement lamp is engineered to handle the continuous punishments of long-haul transport.
Dual-Bulb Backup Safety & Vibration-Absorbing Shock Mount
Eliminate the risk of immediate roadside citations or unsafe blind spots caused by a single burnt filament. The Truck-Lite 29204C 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 fully legal until your next scheduled maintenance window. Additionally, this fixture features a built-in heavy-duty shock mount that absorbs severe road impact and continuous chassis vibration, significantly extending the service life of the internal incandescent filaments.
Sonically Sealed Polycarbonate Infrastructure
To defend against heavy rear-road spray, swirling dust, wash-down pressure, and corrosive winter chemicals, the lens and housing are sonically welded together from high-impact clear polycarbonate. This forms a permanent, one-piece barrier that eliminates internal lens fogging and moisture-related short circuits. Electrical routing is simplified and made corrosion-proof thanks to an integrated 2-prong male pin connector (utilizing an industry-standard plug layout common to Stop/Turn/Tail wiring systems). Designed for a seamless 2-screw surface mount configuration, it cleanly bolts directly onto existing fleet brackets or license frames.
