Truck-Lite 18050Y – 18 Series LED Yellow Rectangular 3-Diode Marker Clearance Light, P2, 2-Screw Mount, Reflectorized Diamond Shell, Hardwired, Blunt Cut, 12V, Kit

High-Efficiency 3-Diode LED Array: Engineered to provide maximum amber light output with a minimal electrical current draw, reducing overall strain on your vehicle's alternator.

Integrated Diamond Shell Reflector: Features a highly effective reflectorized lens design. When mounted properly, it complies with strict safety standards for a legal reflex reflector, keeping your trailer visible even when parked or unpowered.

Vibration-Resistant Solid-State Build: Because LEDs have no brittle filaments to break, this light is exceptionally resistant to the grueling shock and vibration of heavy commercial hauling.

Hassle-Free Retrofit Installation: Uses standard 2-screw mounting holes and footprint spacing, making it a quick, direct replacement upgrade over older, dim incandescent fixtures.

Weatherproof Sealed Acrylic Housing: The scratch-resistant, fade-resistant yellow acrylic lens and housing are sonic-welded together to permanently lock out moisture, dust, and corrosive road grime.

Universal Blunt Cut Connection: Comes hardwired with a 2-wire, 18-gauge blunt-cut wiring harness plug side, allowing for clean, reliable splicing into your existing 12V system.

Full DOT & FMVSS Compliance: Certified to meet rigorous FMVSS 108, CMVSS 108, DOT, and SAE standards for P2 and "A" (Reflector) ratings.
