Truck-Lite 40637 – 40 Series Left-Hand LED Stop/Tail/Turn & Marker Clearance Light Module Assembly (Black Steel Box Mount, Fit 'N Forget S.S. Connection, 12V)
Equip the driver-side of your vehicle with maximum lighting power and physical defense using the heavy-duty Truck-Lite 40637 40 Series Left-Hand LED Stop/Tail/Turn (S/T/T) and Marker/Clearance Light Module. Engineered for direct structural integration onto heavy-duty commercial semi-trucks, vocational trailers, box vans, and flatbeds, this universal-mount assembly wraps elite LED performance in a rugged, crash-resistant protective enclosure.
This heavy-duty left-hand vehicle module combines a 4-inch round Super 44 LED Stop/Tail/Turn Light Head, an integrated LED Side Marker Clearance Lamp, and a Built-in Red Reflector Panel. The entire electrical assembly comes pre-installed inside an ultra-tough, black powder-coated structural steel mounting box. To provide elite weather defense, the internal light heads are sonically sealed and fully epoxy-encapsulated. This design locks out harsh moisture, dust, and corrosive road salts while completely isolating the electronics from chassis vibration and heavy field impacts.
