Nilight 2-Pack Rectangular Submersible LED Trailer Lights — IP68 Waterproof, License Plate & Multi-Function

Nilight 2PCS Rectangular Submersible LED Trailer Light Kit is a fully sealed, multi-function 12V lighting set designed to deliver durable tail, brake, turn, side marker and license plate illumination for trailers, boats and other 12V vehicles.

These rectangular LED lamps combine low power draw with high visibility in a compact, waterproof housing rated IP68. The kit includes two lamps (left and right), a license plate bracket, 25 ft of trailer wiring harness and stainless steel mounting hardware — everything needed for a straightforward retrofit or replacement. Built for marine and road environments, the lights are designed to resist immersion, vibration, and the wear that comes from frequent use.

How bright and efficient are these Nilight LEDs?

The lamps use multiple high-output diodes to produce bright signals while consuming less current than incandescent bulbs. The left lamp incorporates additional diodes dedicated to license plate illumination, ensuring plate legibility at night. DOT-compliant LEDs help maintain visibility without overtaxing the vehicle electrical system.

• Left lamp: 27 diodes including 9 dedicated license plate LEDs
• Right lamp: 12 diodes for tail/brake/turn functions
• Lower amperage than incandescent bulbs for reduced draw
• DOT-compliant light output suitable for on-road use

Will these lights survive water, salt, and road spray?

The Nilight kit is engineered for harsh wet conditions; the internal LEDs and circuit board are fully encapsulated to prevent shorting when submerged. The external housing includes features that help manage water drainage and block intrusion, making these lights suitable for boat trailers, marine use, and vehicles frequently exposed to rain or splashes.

• IP68-rated submersible seal protects internal electronics
• Water-drainage features reduce standing moisture
• Stainless steel mounting hardware resists corrosion
• Designed to withstand salt and fresh water exposure

How easy is installation and what’s included in the kit?

This kit is designed for a straightforward installation: lights mount left and right with the license plate lamp on the left side. Wiring follows a color-to-color connection with the white wire to chassis ground. The package supplies the lamps, a license plate bracket, a 25-foot trailer harness and various stainless fasteners so you can complete the job without sourcing extra parts.

• Complete kit: lamps, bracket, 25 ft harness, hardware included
• Color-coded wiring: match wire colors and connect white to ground
• Mounting advice provided in included diagrams and photos
• Hardware fits common trailer thicknesses and installations

Are these lights compatible with my trailer or vehicle?

The lamps are made for 12V DC systems and are suitable for trailers with a maximum width of roughly 80 inches, as well as many trucks, RVs, boats, campers and work equipment. Verify your vehicle’s wiring and mounting space before buying, and consult the included wiring diagram if unsure.

• Designed for 12V DC electrical systems
• Recommended for trailers up to about 80 inches wide
• Works with boats, RVs, pickups, campers, tractors and more
• Check local regulations for required lighting configurations

Who is this for: This Nilight submersible rectangular LED kit is intended for boaters, trailer owners and vehicle operators who need reliable, low-maintenance signal lighting that tolerates immersion and harsh conditions. It’s a practical choice for anyone replacing worn incandescent trailer lights, upgrading to LEDs for improved power efficiency, or equipping marine trailers and vehicles exposed to water and road debris.
