Partsam LED Trailer Light Kit — 2pc Waterproof Square Red Stop/Turn/Tail with Steel Mounting Boxes

Partsam 2-piece waterproof square LED trailer light kit provides bright red stop, turn, tail, side marker and license illumination in a sealed IP68 housing with heavy-duty steel mounting boxes.

Upgrade your under-80" trailer, boat, truck or RV lighting with a compact, durable set engineered for visibility and weather resistance. This kit includes left and right multi-function LED assemblies (one with integrated license plate illumination), matched black 45-gauge steel mounting boxes, and a license bracket with screws. It’s designed to replace conventional bulbs with low-draw LEDs that stay visible in rain, spray, and road grime.

How do these lights improve visibility on the road?

The LEDs use multiple diodes arranged to produce crisp, consistent red output for stop, turn and tail functions while built-in reflectors add passive visibility when lights are off. One side includes white LEDs focused on the license plate, ensuring the plate stays illuminated for compliance and safety. The high LED count helps maintain even brightness across the lens so other drivers see clear signals.

• 15 diodes on curbside unit (12 red + 3 red reflectors)
• 19 diodes on street side unit (12 red + 3 red + 4 white license LEDs)
• Integrated reflectors to boost passive visibility
• Super-bright LEDs for clearer signaling day or night

Are these lights durable and weatherproof?

Yes — the assemblies are fully sealed to meet IP68 standards, which protects the internal circuitry from heavy water exposure and dust. The acrylic lens and sealed housing prevent intrusion, so the lights remain functional after immersion or prolonged wet conditions. Combined with robust steel mounting boxes, the system resists vibration and mechanical wear on working vehicles.

• IP68-rated sealed acrylic lens and housing
• Heavy-duty 45-gauge S45C (1045) steel mounting boxes
• Designed for continuous outdoor exposure and road spray
• Low-maintenance LEDs reduce bulb replacement

What vehicles and installations are these lights compatible with?

This kit is sized and configured for trailers and towing rigs under 80 inches wide, making it suitable for many common applications from utility trailers to campers. The package includes a left and right lamp, the steel mounting boxes and a license plate bracket with screws to simplify retrofit installs. Wiring follows standard 12V trailer circuits for stop, turn and tail functions.

• Universal fit for trailers, boats, RVs, trucks, campers under 80"
• Works with standard 12V trailer wiring systems
• Includes mounting boxes and license bracket for direct replacement installs
• Designed for curbside and street-side lamp positions

How easy is the installation and maintenance?

Installers will find the kit straightforward: mount the steel boxes in the trailer body, secure the lamps and connect to the existing 12V wiring. The screws and bracket are included so the license light is ready to go, and the sealed LED units require little ongoing maintenance compared with incandescent bulbs. Because LEDs have a long service life, expect fewer replacements and lower power draw.

• Includes screws and license plate bracket for quick mounting
• Directly replaces most square trailer light cutouts
• Low-power LEDs mean less current draw and longer life
• Sealed construction minimizes routine upkeep

Who this is for: This Partsam kit is built for owners and operators who need reliable, bright trailer lighting that stands up to wet conditions and heavy use — including trailer fleets, boat owners, RV enthusiasts, and anyone upgrading old incandescent trailer lamps. It’s especially useful for installations where a durable steel backing and integrated license illumination are required.
