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

Partsam 12V Submersible Smoked Red Square LED Trailer Lights are waterproof, DOT-compliant combo stop/tail/turn lights designed for boat trailers and vehicles under 80" wide. These compact square LED lamps combine high-visibility illumination with a smoked housing for a sleek, modern look while meeting road-legal requirements. Built with sealed circuit boards and durable materials, they resist water intrusion and salt exposure, making them suitable for launch ramps, marine use, and year-round trailering. Each set includes left and right combination lamps with integrated reflectors and a three-wire pigtail for straightforward wiring.

How do these lights perform when submerged or exposed to harsh weather?

These lights are engineered to keep working after repeated exposure to water. The circuit board and LED diodes are fully sealed to IP68-level protection, minimizing corrosion and shorting risks even when a trailer briefly goes underwater.

• IP68-style sealed housing resists immersion and moisture
• Corrosion-resistant materials for marine environments
• Sealed LED diode assembly prevents water damage to electronics

What lighting functions are included and how are they distributed between sides?

The pair provides full rear-light functionality with slightly different diode counts per side to add a license-illumination feature. The curb-side (passenger) lamp supplies six functions, while the street-side (driver) lamp adds a license plate illuminator for seven functions total.

• Passenger side: stop, turn, tail, rear reflector, side marker, side reflex reflector
• Driver side: stop, turn, tail, rear reflector, side marker, side reflex reflector, license plate light
• Distinct diode counts create solid, high-visibility light patterns

How does installation and wiring work on typical trailers?

Installation is straightforward for anyone familiar with trailer lighting. Each lamp uses a three-wire pigtail; wires are color-coded for ground, turn/stop, and tail/marker functions so you can splice into existing trailer harnesses or connect to a new wiring harness.

• Three-wire pigtail: ground plus separate circuits for high- and low-brightness sides
• Surface-mount footprint fits most trailer rear mounting locations
• Comes as a left/right pair ready for hardwiring into your trailer wiring system

Will these lights fit my trailer and meet legal requirements?

Designed for trailers under 80 inches wide, these lights fit common rear mounting points and include reflectors to meet visibility rules in many jurisdictions. They are DOT-compliant as combination stop/tail/turn units, but always confirm local regulations and mounting height requirements before installation.

• Recommended for trailers, boats, RVs, campers, snowmobiles, and utility trailers under 80" wide
• Integrated reflectors improve passive visibility when lights are off
• Smoked lens offers a modern appearance while maintaining legal light output

Who is this for These Partsam submersible square LED trailer lights are best for boat owners, haulers, and outdoor enthusiasts who need reliable, weatherproof rear lighting without sacrificing style. Choose them if you launch or retrieve trailers regularly, tow in wet or salty conditions, or want a compact DOT-compliant replacement with a smoked aesthetic and easy hardwired installation.
