Partsam 12V Submersible Square LED Trailer Lights 2-Pack, Red/Clear Lens, IP68 Waterproof

Partsam 12V submersible square LED trailer lights combine stop, turn, tail, reverse and side-marker functions in a single IP68-rated unit for reliable trailer illumination.

These compact square lamps pack red and white LEDs into a weatherproof housing built for salt spray, mud and rain. Designed for trailers under 80", trucks and utility vehicles, each lamp delivers distinct high- and low-brightness circuits plus a dedicated reverse light. The set includes two lights, mounting gaskets and screws for a straightforward retrofit.

How bright and visible are these lights on busy highways?

The LEDs use a multi-diode layout with separate color banks for signaling and reversing, producing clear, recognizable illumination both day and night. High-brightness diodes handle stop/turn duties while low-brightness diodes run as tail/marker lights for consistent visibility.

• Left lamp: 21 diodes (13 red + 8 white) for combined stop/turn, reverse and license illumination.
• Right lamp: 18 diodes (10 red + 8 white) optimized for stop/turn and reverse functions.
• Distinct white reverse LEDs improve backup visibility without overpowering tail signals.

Are these lights durable and weatherproof for marine or off-road use?

Yes — the lamps use impact-resistant polycarbonate lenses and ABS housings with an IP68 rating to keep water and dirt out of the electronics. The sealed build is intended for prolonged exposure to harsh conditions commonly encountered on trailers and utility vehicles.

• IP68 waterproof protection against immersion and heavy splashes.
• PC lenses resist impact and abrasion; ABS housing adds structural durability.
• Sealed wiring entry points reduce corrosion risk in marine environments.

How do I wire and install these multi-function trailer lights?

Wiring follows common trailer-color conventions so installation is straightforward for anyone familiar with trailer electrics. The package contains mounting screws and gaskets; a separate wire harness is required but not included.

• White = ground; connect to vehicle/chassis earth.
• Yellow/Green = high brightness stop/turn circuit.
• Brown = low brightness tail/marker/license (left lamp only provides license light).
• Blue = reverse/backup light circuit.

Will these lights fit my trailer and what’s included in the kit?

The compact square shape is compatible with most trailers under 80" and a broad range of commercial vehicles. The set includes everything needed for mounting but not the vehicle-side wiring harness.

• Two square LED tail lights with red/clear lenses.
• Mounting gaskets and screws for a sealed installation.
• Clear wiring color guide printed for each function (wire harness sold separately).

Who this is for: These Partsam square LED trailer lights suit DIY trailer owners, small-fleet operators and anyone replacing worn or non-waterproof lamps on boat, utility, or cargo trailers. If you need an all-in-one stop/turn/tail/reverse lamp with strong ingress protection and a compact footprint, this kit is a practical, weather-resistant upgrade that keeps signaling clear and dependable on roads and ramps.
