Partsam Square 12V Submersible LED Trailer Lights, Black/Clear Lens, IP68 Waterproof Dual-Function Set

Partsam 12V Submersible Square LED Trailer Lights are a compact, multi-function waterproof lighting solution for trailers, trucks, and utility vehicles under 80" that combines stop/turn, tail, reverse and side-marker functions in one durable unit.

These square LED lamps deliver bright, visible lighting in a slim, impact-resistant housing rated IP68 for full submersion protection, making them suitable for boat trailers, utility trailers, dump trucks, and other tow vehicles. Each unit packs a mix of red and white diodes to perform stop/turn, running/tail, reverse/backup and marker duties; the left lamp also includes a license plate light. The set includes two lights, gaskets, and mounting screws for straightforward installation—wire harnesses are not included.

How do these lights handle wet or harsh conditions?

Engineered for heavy-duty exposure, the lights use an ABS housing and impact-resistant polycarbonate lens to resist physical damage. Their IP68 rating means the fixtures are sealed against dust and can withstand continuous immersion, protecting internal circuitry when launching boats or driving through deep puddles.

• IP68 waterproof rating for full submersion protection
• Impact-resistant PC lens to resist chips and cracks
• ABS housing resists corrosion and road debris
• Sealed cable entry and included gaskets for reliable mounting

What lighting functions are included and how bright are they?

Each light integrates multiple functions: stop/turn, tail/marker, and reverse. The left-side lamp also provides a white license plate illumination. The diodes are arranged to separate red and white outputs for clear, distinct signals to other drivers.

• Left: 21 diodes (13 red + 8 white) for stop/turn, reverse, tail, and license plate
• Right: 18 diodes (10 red + 8 white) for stop/turn, reverse, and tail
• Distinct white LEDs for bright reverse illumination
• Balanced red LEDs for visible stop/turn and tail output

How do I wire and install these square trailer lights?

Wiring is color-coded for straightforward connection to a trailer harness; a basic knowledge of trailer electrical systems is helpful since a separate harness is not included. The package supplies mounting screws and gaskets; position the gasket, secure the lamp to the mounting surface, and attach wires to the trailer's circuit according to function colors.

• White wire = ground (negative)
• Yellow/green wire = high brightness (stop/turn)
• Brown wire = low brightness (running/tail/side marker/license plate)
• Blue wire = reverse/backup light

Will these lights fit my trailer or truck?

These square lamps are designed as universal replacements for many vehicles and trailers under 80 inches, including boat trailers, utility trailers, small trucks, and agricultural equipment. Check your mounting hole pattern and electrical connector compatibility before purchase; adapters or minor drilling may be required for some installations.

• Intended for trailers under 80" and many truck/trailer applications
• Compact square footprint for tight mounting locations
• Surface-mount installation with included screws and gaskets
• Common wiring colors for easy integration with standard harnesses

Who is this for: Owners of trailers, boaters, contractors, and fleet operators who need a compact, rugged, multi-function taillight with strong waterproofing and clear reverse illumination. These lights suit anyone replacing worn lenses or upgrading to LEDs for longer life, lower current draw, and improved visibility in wet or low-light conditions. If you need a full harness or plug-and-play connectors, plan to acquire the correct wiring harness or adapter separately.
