Partsam Submersible Square LED Trailer Light, Red/White 2-Pack — IP68 DOT Compliant, Stop/Turn/Tail & License

Partsam 12V Submersible Square LED Trailer Light is a waterproof, DOT-compliant stop/turn/tail and license lamp designed to upgrade visibility on trailers, boats, RVs and utility vehicles under 80".

These compact square LED modules combine high-brightness diodes, a sealed acrylic lens and a multi-function design to provide bright stop, turn, tail, side marker and license plate illumination. Constructed for marine and road use, the lights are IP68-rated and built to resist water, vibration and road grime. Each package includes two lamps, gaskets and mounting screws so you can replace or upgrade factory lights quickly; a harness is not included.

How do these lights improve visibility on trailers and boats?

Partsam’s LEDs deliver clearer signaling and improved side-marker presence compared with incandescent bulbs. The combination of red and white diodes ensures brake, turn and tail signals are distinct while a dedicated white array illuminates the license plate on the street-side unit.

• 15 or 19 diode layouts for curb and street sides respectively
• Dedicated white LEDs on street side for license illumination
• Bright, long-lasting LEDs for consistent signaling day and night
• Reflectors integrated to boost visibility when lights are off

Are these lights durable enough for marine and off-road conditions?

Yes — the lamps are fully sealed with an acrylic lens and rated IP68 for submersion resistance, protecting the circuitry from moisture and salt. Their heavy-duty build handles vibration and impact typical of trailers, snowmobiles and boats.

• IP68-rated waterproof construction for prolonged water exposure
• Acrylic lens engineered to keep water out and protect LEDs
• Robust housing suitable for trucks, campers and marine use
• DOT compliant for legal road use where required

How easy is installation and what’s included?

Installation is straightforward for most trailer owners with basic wiring skills. The kit ships with two square lights, rubber gaskets and four mounting screws; you’ll need to supply or reuse a compatible wire harness to connect to your vehicle’s wiring.

• Package contains 2 lights, 2 gaskets and 4 screws (harness not included)
• Mounting uses supplied screws and gasket for a watertight seal
• Wiring follows standard brake/turn/tail/ground conventions
• Fits trailers under 80", trucks, RVs, boats and special vehicles

Which functions does each light perform and how do they differ?

Each side unit covers multiple signaling roles. The curb-side (passenger) light uses 15 diodes to serve stop, turn, tail, side marker and reflector functions. The street-side (driver) light adds a white LED cluster for license plate illumination alongside the same red-signal functions.

• Curb side: 15 diodes (12 red + 3 red) for 6 functions including tail and marker
• Street side: 19 diodes (12 red + 3 red + 4 white) adding license light for 7 functions
• Both units include rear and side reflex reflectors
• Works as stop, turn, tail, side marker and license illuminator (street side)

Who is this for: These Partsam square submersible LED lights suit trailer owners, boaters, RV and camper operators, snowmobile and utility-trailer users who want brighter, weatherproof lighting that meets DOT requirements. They’re a practical upgrade for anyone replacing worn or dim incandescent lamps, preparing a trailer for wet conditions, or seeking a compact multi-function lighting solution for vehicles under 80".
