Truck-Lite 33206Y 33 Series LED 0.75" Round 1-Diode Yellow Marker Clearance Light Kit – Dual Function, Black Rubber Closed-Back Grommet, Hardwired 12V

Upgrade your commercial vehicle, fleet, or trailer with the Truck-Lite 33206Y 33 Series LED Yellow Round Marker Clearance Light Kit. Widely celebrated as the world’s smallest LED marker lamp for the commercial transportation industry, this highly versatile 0.75-inch, 3-wire light delivers high-impact safety in a miniature package. When properly installed, it provides critical dual-function performance, serving seamlessly as a side marker, clearance light, auxiliary turn signal, and auxiliary stop light. Engineered with a best-in-class auxiliary brake function that glows seven times brighter than the standard baseline marker mode, it gives nearby drivers immediate, unmistakable visibility during stops and turns.

Engineered to withstand the punishing road conditions faced by heavy-duty trucks and commercial trailers, the Truck-Lite 33206Y is built for survival. Its advanced electronics are completely encapsulated and sealed in protective epoxy to aggressively resist water penetration, moisture buildup, road salt, and corrosion. The solid-state, non-filament LED design ensures that the light is entirely immune to harsh shock, severe chassis vibration, and mechanical impacts. Encased in a high-temperature, impact-resistant yellow polycarbonate lens and paired with a premium black rubber closed-back grommet mount, this kit prevents physical damage and heat entrapment, substantially lowering your vehicle's long-term maintenance costs.

Upgrading from outdated, power-hungry incandescent bulbs is completely hassle-free. The hardwired 3-wire system comes standard with slim-line .180 male bullet terminals, allowing for quick, plug-and-play retrofitting into any standard 3/4-inch mounting hole. Because modern LEDs operate on minimal current (Major: 0.12 Amps / Minor: 0.03 Amps), this multi-function lamp lightens the alternator's electrical load, preserving your battery life and freeing up power for other heavy-duty auxiliary systems.
