Partsam LED Trailer Light Kit Halo Glow Submersible Square Pair — DOT‑Compliant Waterproof Tail Lights

Partsam 12V Halo Glow submersible square LED tail light kit is a DOT-compliant, waterproof left/right pair that combines distinct halo styling with seven trailer lighting functions for boats, RVs, and trailers under 80 inches.

These Partsam square LED tail lights are built to withstand immersion, resist vibration, and make your trailer more visible with a distinctive solid-halo appearance. Each sealed unit integrates multiple LEDs and a 3-wire pigtail for straightforward hardwiring to common 12V trailer systems. Designed for surface-mount installation, the lights meet DOT standards and are suitable for marine, RV and utility trailer use where occasional submersion or wet conditions occur.

How durable are these lights in wet or marine conditions?

The Partsam lights feature a sealed circuit board and waterproof housing that protect diodes and electronics from moisture and spray. Their submersible rating and rugged surface-mount construction help them tolerate trailer launches and road exposure without failing.

• Fully sealed PCB to prevent water damage
• Submersible design for boat trailer use
• Surface-mount LEDs resist shock and vibration
• DOT-compliant housing for road legality

What lighting functions does the kit provide?

Each tail light performs seven common trailer lighting roles: brake, tail, turn signal, side marker, side reflector, rear reflector and license plate illumination on the street side. The combination of red and white diodes delivers clear signaling plus a licensed plate illuminator where required.

• Brake, turn and tail signals integrated
• Side marker and reflector built into lens
• Street-side unit includes white license lamp

How easy is installation and wiring?

Installation is straightforward: these are surface-mount lights with two mounting studs spaced 2 inches on center and a three-wire pigtail for direct connection to your trailer harness. The color-coded wires simplify hookup to ground, tail, and brake/turn circuits.

• 3-wire pigtail: white ground, gray tail, red brake/turn
• 2" center-to-center mounting studs for common brackets
• Surface-mount profile avoids extra drilling through panels
• Soldered surface-mount LEDs reduce wiring stress points
