Nilight Square Submersible LED Trailer Light Kit, 2-Piece IP68 Waterproof, 7-Function with 25ft Harness

Nilight Square Submersible LED Trailer Light Kit is a two-piece, IP68-rated, seven-function lighting system designed for trailers, boats, RVs and other 12V vehicles.

This kit combines compact square taillights with an amber clearance lamp, a license-plate bracket, stainless mounting hardware and a 25-foot color-coded wiring harness so you can replace or upgrade rear lighting quickly. Each lamp houses multiple LEDs and a sealed circuit board to deliver bright, low-current illumination that stands up to water, road spray and harsh outdoor conditions.

How does this kit serve all rear lighting needs?

The Nilight set integrates seven essential light roles—stop, turn, tail, side marker, reflectors and license illumination—into a pair of compact assemblies plus an amber side lamp. That means fewer separate fixtures and a cleaner, simpler rear wiring layout on trailers up to 80 inches wide.

• Seven combined functions in two square lights and one amber clearance lamp
• Includes reflective elements for passive visibility when lights are off
• Designed for 12V DC vehicle electrical systems and common trailer widths
• All necessary brackets and mounting hardware included for immediate installation

What makes these LEDs safer and more efficient than incandescent bulbs?

The lights use efficient LED chips that draw less current while producing bright output, improving visibility and reducing load on your electrical system. LEDs also resist vibration and shocks better than filaments, so they last longer in towing and marine environments.

• Low amperage draw preserves battery and fuse capacity
• Bright, focused LED arrays improve brake and turn awareness for following drivers
• Longer operational life compared with traditional incandescent lamps
• DOT-compliant brightness and function layout for road use

Is the kit truly waterproof and suitable for submersion?

The assemblies are sealed with an IP68 rating, meaning the internal LEDs and circuit board are protected against full submersion and heavy water exposure. Additional drainage features in the housing reduce the chance of trapped moisture, making the set suitable for boats, splash-prone trailers and wet climates.

• IP68-rated waterproof sealing around LEDs and circuit board
• Housing design includes water drainage to prevent pooling
• Corrosion-resistant stainless mounting hardware for marine use
• Suitable for frequent wet conditions and occasional submersion

How straightforward is installation and wiring?

The kit comes as a full plug-and-play package with a long, color-coded 25-foot wiring harness and clear mounting parts so you can install it without hunting for extras. Stud-style surface mounts simplify mechanical attachment, while the harness and printed instructions guide wire matching and grounding.

• 25-foot color-coded harness for flexible routing and easy hook-up
• Stud-mounted lights for secure surface attachment
• Step-by-step wiring color match: color-to-color, white to ground
• Includes license-plate bracket and multiple stainless fasteners

Who is this for: This Nilight kit is intended for trailer owners, boaters, RVers and light-duty commercial vehicle operators who need a compact, weatherproof rear lighting solution that combines multiple functions. If you want bright, low-draw LEDs with submersible protection and a complete hardware-and-harness package for simple installation, this set fits trailers, pickups, campers, utility trailers and marine applications.
