Partsam LED Trailer Light Kit 2-Piece Red Square Stop/Turn/Tail — IP68 Waterproof, DOT-Approved

These compact square lamps combine bright LEDs, an acrylic waterproof lens and rugged 45-gauge S45C 1045 steel mounting boxes to provide reliable rear lighting for trailers, trucks and RVs under 80 inches wide. The pair includes left and right combo lights with integrated reflectors and a license plate illuminator on the passenger side, plus a license bracket and mounting screws for straightforward installation. Rated IP68 and built to DOT standards, the set is intended for long-lasting exterior use in wet or dusty conditions.

What exactly does each light do on the trailer?

Each lamp is a multi-function combination light designed to replace several separate fixtures. The curbside (driver) unit covers stop, turn, tail, rear reflector and side marker functions; the street-side (passenger) lamp adds a white license plate illuminator on top of those features.

• Driver side: stop, turn, tail, rear reflex reflector, side marker, side reflex reflector.
• Passenger side: stop, turn, tail, rear reflex reflector, side marker, side reflex reflector, license plate light (white LEDs).
• LED counts: driver 15 diodes (12 red + 3 red reflector diodes); passenger 19 diodes (12 red + 3 red + 4 white).
• Includes integrated reflectors for passive visibility when lights are off.

How durable and weatherproof are these lights?

Durability is built into both the lamp and the housing: the box is formed from heavy-duty S45C 1045 steel at 45 gauge thickness and the lens is sealed to an IP68 standard so water and dust stay out. The fully sealed acrylic lens and robust steel mounting boxes protect the LED circuits for reliable operation in rain, splashes and road grime.

• Housing: 45 gauge S45C 1045 carbon steel (0.04" thickness) for impact resistance and mounting strength.
• Ingress protection: IP68 rating—submersible and dustproof sealing around LEDs and wiring.
• Lens: acrylic material engineered to prevent water intrusion and maintain optical clarity.
• Temperature and road-ready: designed for exterior exposure on trailers and trucks.

What does installation look like and what’s included?

The kit ships with a left and right sealed LED lamp, two black steel mounting boxes, a license plate bracket and mounting screws so you can fit it into an existing under-80" trailer layout. Basic wiring and mounting steps are straightforward for a mechanic or DIY installer familiar with trailer lights.

• Included items: 2 LED lights (left + right), 2 steel mounting boxes, license plate bracket, mounting screws.
• Voltage: 12V system compatibility for most towing vehicles and trailers.
