6 Inch Trailer Lights LED Kit - Submersible Boat Trailer Lighting

In this review the 6 Inch Trailer Lights LED Kit is evaluated as a practical, waterproof replacement lighting solution for boat and utility trailers. The kit's single biggest selling point is its fully submersible design combined with bright, low-power LED arrays, which makes it especially useful for anyone who regularly launches or retrieves trailers in wet conditions. Installation requires attention to the four-wire color convention, so buyers who are comfortable with basic trailer wiring will appreciate the straightforward harness and complete mounting hardware included.

Key Features

• Submersible construction: Epoxy encapsulated electronics and a sonic sealed PCB provide a fully welded sealed light that stands up to immersion and bad weather.
• Four-wire function: Separate white ground and color-coded brown/yellow/blue wiring allow clear tail, left and right signal/brake wiring for reliable trailer control.
• All LED diodes: LED arrays provide bright output with lower power draw and no glare compared with incandescent bulbs.
• Dual-side LED counts: Driver side has 34 LEDs including a 9-LED license area, while passenger side has 25 LEDs, contributing to strong visibility.
• Complete kit: Includes two combination run/stop/tail/turn rectangular lights, a 25 ft 4-pin harness, license plate bracket and stainless steel mounting hardware for an all-in-one install.
• DOT compliance: Designed to meet FMVSS-108 taillight requirements, making it suitable for road use on trailers over 80 in wide.

Who It's For

The kit is best for boat owners, utility trailer users and anyone who needs a waterproof, reliable lighting solution for trailers that are frequently launched or operate in wet environments. Its clear wiring convention and included harness make it a sensible upgrade for DIY installers comfortable with 12V trailer wiring.

People who should look elsewhere are those who require adjustable mounting hardware for nonstandard enclosures or exact-fit replacements for proprietary enclosed fixtures, since a few buyers reported mixed fit with some enclosed boat trailer light housings and limited hardware adjustability.
