Nilight Submersible LED Trailer Light Kit, 2PCS Square IP68 Waterproof — 7-Function DOT-Compliant Rear Lights

Nilight Square Submersible LED Trailer Light Kit is a fully sealed, two-piece 7-function LED lighting system built for trailers, boats and other 12V vehicles that can be submerged without shorting.

This kit combines durable construction, DOT-compliant brightness and a complete set of installation parts so you can replace or upgrade rear lighting on trailers, RVs, pickups or marine crafts. Each square lamp integrates stop, turn, tail, side marker, rear reflector, license illumination and side reflector functions into one compact, submersible housing. The package includes a 25ft wiring harness, license bracket, amber clearance light and stainless mounting hardware for a straightforward retrofit.

How does this light perform in wet or submerged conditions?

Nilight designed the lamps to endure immersion with an IP68-rated seal that protects the LEDs and circuit board from water ingress. The enclosure also routes water away via a drainage design so trapped moisture won't compromise electronics. This makes the lights suitable for boat trailers and other applications where contact with water is frequent.

• IP68 fully submersible LED assembly for underwater exposure
• Sealed internal circuit board and LEDs to prevent shorts
• Housing drainage features reduce trapped moisture risk

What lighting functions and brightness can I expect?

Each square lamp delivers seven combined functions: stop, turn, tail, side marker, side reflector, rear reflector and license plate light—so you get full rear lighting coverage from two fixtures. The LEDs run efficiently, drawing less current than incandescent bulbs while producing a clear, high-visibility output that meets DOT standards for road use.

• Seven integrated functions in one compact unit
• High-efficiency LEDs for strong visibility and lower amperage draw
• 100% DOT-compliant brightness for legal on-road use

What comes in the kit and how hard is it to install?

The package is intended to be all-inclusive for typical trailer installs: two square submersible lights, an amber clearance lamp, a license plate bracket, a 25ft trailer wiring harness, reflectors and assorted stainless mounting hardware. Mounting uses stud-style surface attachment and color-coded wiring simplifies hookups—match wires color to color and attach the white ground to the vehicle frame.

• Complete 2-piece light set with license lamp and reflectors
• 25ft, color-coded wiring harness for flexible routing
• Stainless mounting hardware and bracket included for reliability

Will these lights fit my trailer or vehicle?

The lights are designed for 12V DC systems and are suitable for trailers up to about 80 inches wide, plus a wide range of vehicles including boats, RVs, pickups, tractors and utility trailers. Confirm your mount hole spacing and that your vehicle’s electrical system is 12V before ordering.

• Compatible with 12V DC vehicle electrical systems
• Recommended for trailers with maximum width around 80 inches
• Fits many vehicle types: trailers, boats, RVs, pickups, tractors

Who is this for: This Nilight kit is aimed at trailer owners, boaters and fleet operators who need compact, durable rear lighting that withstands wet environments and simplifies replacement. It’s especially helpful when you want a sealed, low-current LED upgrade with all required hardware and a long wiring harness included—ideal for marine trailer use, utility trailers that encounter water, and anyone seeking DOT-compliant LED rear lights without complex wiring runs.
