Partsam 12V Halo Glow Submersible Square LED Trailer Light Kit L/R for <80" Boat Trailer RV Camper DOT Waterproof

The Partsam 12V Halo Glow submersible square LED trailer light kit provides DOT-compliant left and right stop/turn/tail illumination with a distinctive halo effect and sealed waterproof construction for boat trailers and small tow vehicles.

Designed for trailers under 80 inches wide, this twin light set replaces standard square tail lamps with a stylish halo-style solid light pattern that improves visibility and adds a modern look. Each lamp combines multiple LED arrays to perform brake, turn, tail, side marker, rear reflector and license plate illumination while a fully sealed circuit board resists moisture and submersion—ideal for marine use and wet towing conditions.

How does this kit perform in wet or marine environments?

These lights were built to withstand splashes and brief submersion thanks to a sealed PCB and waterproof housing. The diodes and solder joints are protected from water intrusion, reducing failure risk when launching or retrieving boats.

• Fully sealed circuit board prevents water damage to LEDs
• IP-grade style waterproofing suitable for boat trailers
• Corrosion-resistant housing and hardware for marine use

What lighting functions does each unit provide?

Each square light supports seven functions: brake, tail, turn, side marker, side reflector, rear reflector and a license-illuminator on the street-side lamp. The two lamps have slightly different diode counts to include a white license light on the passenger side.

• Driver side: 32 LEDs (red-focused) for stop/turn/tail and reflectivity
• Passenger side: 38 LEDs including white diodes for license illumination
• Visible solid halo pattern for consistent signaling and styling

How is the kit wired and mounted to my trailer?

The kit uses a simple 3-wire pigtail for straightforward hardwiring into existing trailer circuits: ground, tail, and combined brake/turn. These are surface-mount lights with 2-inch center mounting studs designed to extend from the mounting surface for easier installation and serviceability.

• 3-wire pigtail: white = ground, gray = tail, red = brake/turn
• Surface-mount design with 2" mounting stud spacing
• Plug-and-splice friendly for common trailer wiring harnesses
