Special Function: Use as an LED marker light, rear side roof light, or LED marker light indicator on any 12V pickup truck, SUV, RV, camper van, minivan, truck, bus, etc. Upgraded LED Light: Uses 3 high-quality Piranha LEDs with improved heat dissipation, a wider beam angle, higher brightness, and a longer lifespan, making the light super durable and producing an excellent amber glow. Excellent Reflector Design: This marker light adopts a multi-faceted micro-reflective reflector design to increase light output and add a sophisticated look. Highly Waterproof: The lens and housing are sound-welded, and the internal LED surface is sealed. Be prepared for all weather conditions. Simple Installation: The black wire is for ground, and the red wire is for positive. Simply attach the black base using the two included flat-head screws and snap the light into the base. To pass the rear wires through, you can either drill the central hole, or use washers when attaching the base to create space to pass the wires through without drilling the central hole.
