Boat Trailer Lights LED Submersible Kit - Waterproof 29ft Wiring

Our review of the Boat Trailer Lights LED Submersible Kit finds it best suited for owners of small trailers and boat trailers who need a bright, waterproof lighting solution. The single biggest reason to buy is its IP68 submersible design paired with a complete 29ft 4 way wiring harness, which makes it a practical, all-in-one replacement for corrosion-prone factory lights. Installation is straightforward for anyone comfortable with basic trailer wiring and the kit bundles the common parts needed to finish the job without multiple trips to the parts store.

Key Features

• Submersible IP68: Fully sealed housings and welded lenses protect the lights from sand, dirt and water, extending service life in marine conditions.
• Complete kit: Includes two rectangular combination tail lights, six amber marker lights, a 15' 11 LED center bar and a 29ft 4 way wire so users get everything needed for typical trailer installs.
• Multi-function lights: Each combination light handles stop, turn, brake, reverse and tail functions while the left lamp also illuminates the license plate.
• Durable materials: ABS housing and PC lens construction offer shockproof and dustproof benefits for rough road and launch ramp use.
• Color-coded wiring: The 18 AWG 29ft 4 way harness is color coded to simplify routing and reduce splicing during installation.

Who It's For

This kit is aimed at boat owners, small commercial trailer operators and recreational users who need a waterproof, ready-to-install lighting solution for trailers up to roughly 80 in width. It works well for campers, utility trailers, small boats and snowmobile trailers where corrosion from wet launches is a concern.

Those who should look elsewhere include people needing custom-length or 7-way wiring for RV brake controllers, and buyers seeking metal-bodied lights or a premium assembly finish; a few customers reported mixed build and assembly quality, particularly with screw heads and some wiring details.

Pros & Cons

Pros

• Bright LED output provides clear stop, turn and tail signals for increased visibility.
• IP68 submersible rating and welded lenses resist corrosion from saltwater and mud.
• Comes as a near-complete package with wiring, mounting hardware, license bracket and reflectors for faster installs.
• Color-coded 29ft 4 way harness simplifies wiring runs along the trailer tongue and sides.

Cons

• Assembly and build quality is mixed according to some users, with occasional issues reported around screw heads.
• May not meet needs of users requiring 7-way connectors or heavier-duty metal housings for very large trailers.

Frequently Asked Questions

Is this kit fully waterproof for boat launches?
The lights are rated IP68 and have welded lenses and sealed housings designed to resist corrosion from launches and wet environments.

Does the wiring harness require splicing?
The 29ft color-coded 4 way harness is designed to split at the trailer tongue and run each side without needing to splice into new wire, though you must connect to the tow vehicle plug.

Will this fit large trailers?
These lights suit most 12V trailers up to roughly 80 in width; for heavy commercial trailers or 7-way brake controller setups, select a different wiring configuration.
