Partsam Submersible Square LED Trailer Lights Smoked Red Pair — 12V IP68 Waterproof Stop/Tail/Turn

These smoked-red square LED lamps combine a sharp, modern look with a waterproof IP68-rated construction and multi-function wiring so you can replace worn lights on boat trailers, RVs, utility trailers, snowmobile trailers and other towing rigs. They deliver clear stop/turn/tail signals plus side-marker and reflector functions in a low-profile surface-mount housing with separate curb and street side configurations.

What functions does each Partsam square light perform?

Each fixture is a multi-function combination lamp tailored to its mounting side: a passenger-side assembly with 15 red diodes and a driver-side assembly with 19 diodes including white LEDs for license illumination. Together they serve stop, turn, tail, marker, and reflector roles so a single unit handles several lighting needs.

• Passenger side: 15 diodes (12 red + 3 red) — stop, turn, tail, rear reflector, side marker.
• Driver side: 19 diodes (12 red + 3 red + 4 white) — same functions plus license plate light.
• Both housings include integrated reflectors for added visibility when lights are off.

How does the waterproofing work and why is IP68 useful for trailers?

Partsam seals the circuit board and diodes inside the housing to prevent water intrusion, which protects LEDs even when frequently submerged or spray-exposed during launching and retrieval. The IP68 rating indicates protection against dust and continuous immersion, reducing failure risk on boat trailers and other wet environments.

• Sealed circuit board keeps moisture away from connections and diodes.
• Durable lens and gasketed housing resist saltwater and road spray.
• DOT-compliant design for legal on-road use after water exposure.

How do I wire and mount these surface-mount trailer lights?

Each lamp uses a 3-wire pigtail for straightforward hardwiring into standard trailer harnesses: a ground wire plus two signal wires for low/high brightness and combined functions. They are designed for surface mounting, which keeps installation simple and accessible on most trailer rear corners.

• Passenger wiring examples: white = ground, white+yellow = high-bright front side, white+brown = low-bright three-side operation.
• Driver wiring examples: white = ground, white+green = high-bright front side, white+brown = low-bright two-side operation.
• Surface-mount flange requires through-bolts or screws; unit extends slightly from the mounting plane.

Will these lights fit my trailer and meet regulations?

These Partsam square LEDs are intended for trailers under 80 inches wide and are built to DOT standards for visibility and reflector requirements. They work as direct replacements where a square combination tail light is specified and are suitable for many vehicle types including boats, campers, utility trailers, and snowmobile rigs.

• Designed for trailers under 80" width — confirm mounting hole pattern and clearance.
• DOT-compliant optics and built-in reflectors for legal road use.
• Commonly used on boats, RVs, trucks, vans, caravans and utility trailers.

Who is this for? These Partsam smoked-red square LED trailer lights are made for owners and fleet operators who need durable, submersible combination lamps that look clean and modern while meeting road safety standards. They are especially useful for boat owners, tow-vehicle users, and anyone replacing damaged or corroded rear lighting on trailers that see water, salt, or heavy road use.
