EXERAUO Boat LED Trailer Lights Kit — IP67 Submersible, 25ft 4‑Pin Harness, Fully Sealed Waterproof

This kit combines fully LED signal diodes, robust waterproofing and a long 25-foot wiring harness to keep your trailer lights visible and dependable whether launching a boat, towing a camper, or hauling equipment. The housings use epoxy-encapsulated electronics and sonic-sealed circuit boards so the lights resist water intrusion and continue functioning in rain, splashes and occasional submersion. All diodes are LED to reduce power draw while increasing brightness compared with incandescent bulbs.

How does this kit keep lights working in wet or submerged conditions?

The light assemblies are built with epoxy-encapsulated electronics and sonic-sealed printed circuit boards, creating a welded seal around internal components. With an IP67 rating, the units tolerate immersion in shallow water and withstand driving through rain, splashes and trailer launching situations without shorting.

• Epoxy-encapsulated electronics for corrosion resistance
• Sonic-sealed PCB board to block water ingress
• Welded housing seams for extended durability
• IP67-rated protection for temporary submersion

What wiring and connector setup does the kit use?

The kit includes a 25-foot, 4-pin trailer wiring harness with thick PVC insulation and copper-clad aluminum conductors covered by a braided nylon outer sleeve for abrasion resistance. Wire color functions are labeled so installation is straightforward on most 12 V trailers and towing vehicles with a standard 4-pin connector.

• 25FT 4-pin harness with reinforced PVC and nylon braid
• White wire: chassis ground
• Left side: white+yellow for brake, white+brown for running/license
• Right side: white+green for brake, white+brown for running

How bright and energy-efficient are the LEDs?

All signal diodes are LED, which deliver higher luminous output while reducing current draw versus incandescent lamps. That means clearer brake and running light visibility at night and in poor weather without taxing the trailer’s or tow vehicle’s electrical system.

• Full-LED diodes for brighter, crisper signals
• Lower power consumption than incandescent bulbs
• No filament to break—fewer failures from vibration
• Meets DOT taillight requirements for visibility

How versatile is this kit for different trailers and vehicles?

Designed for 12 V systems, the EXERAUO kit fits a wide range of trailers and vehicles commonly used for towing boats, campers, ATVs and work equipment. The lights are sized and positioned to cover trailers about 80 inches wide, and the harness length accommodates most coupler-to-connector distances.

• Compatible with 12V boat trailers, RVs, campers, trucks, vans and more
• Suitable for trailers approximately 80 inches wide
• 25-foot harness reduces the need for extensions
• Durable materials for marine and road exposure

Who is this for: This EXERAUO Boat LED Trailer Lights Kit is aimed at boat owners, trailer owners and fleet operators who need dependable, water-resistant lighting for frequent launching, coastal or rainy-region towing, and anyone upgrading from incandescent trailer lights. It’s a practical choice for do-it-yourself installers who want clear wiring color codes, a long harness, and rugged, sealed LED assemblies that prioritize longevity and visibility without heavy power draw.
