WoneNice LED Submersible Boat Trailer Tail Light Kit — IP67 Sealed, 25ft Wiring Harness

This kit bundles two bright LED brake/turn tail lights, two amber clearance markers, a 25-foot wiring harness, license plate bracket, mounting hardware and reflective stickers — everything needed to outfit most boat trailers and small towing rigs. The lights use SMD 5050 LEDs for a crisp, high-visibility output and the housings are fully sealed to IP67 standards so the circuitry resists immersion and harsh road weather.

How does this kit protect electronics from water and corrosion?

The lights are molded in sealed ABS housings with waterproof cabling and connectors rated to IP67, which means they withstand temporary immersion in water without allowing moisture into the circuit board. Sealed construction reduces the chance of shorting, corrosion, and premature failure that commonly affect trailer lights used in marine environments.

• IP67-rated seal prevents water ingress during submersion
• ABS housing resists saltwater corrosion and UV exposure
• Waterproof-side markers and fully molded tail light units

Will these lights be bright and reliable for road use?

Yes — the SMD 5050 LED chips deliver intense, even illumination with up to a 50,000-hour expected lifespan. The lamp arrangement produces visible brake, turn, and running light functions without excessive glare, helping maintain safety and compliance for on-road towing.

• SMD 5050 LEDs for high lumen output and even spread
• Multi-function: brake, turn signal, and running light in each tail unit
• DOT-compliant design meets standard visibility requirements

How easy is installation and will the harness reach my trailer?

The kit includes a 25-foot wiring harness split into a main 21.65-foot section and a 3.93-foot pigtail to reach most trailer lengths, plus a license plate bracket and mounting hardware. Clear instructions are included to guide wiring and mounting, and the harness fits common 4- to 7-pin trailer connections with simple splicing or plug-in options.

• 25-foot harness covers typical trailer lengths and layouts
• Complete mounting bag and license plate bracket for fast setup
• Installation guide included for wiring and positioning tips

What vehicles and trailers are compatible with this kit?

This lighting set is designed for a wide range of small towing platforms — boat trailers, utility trailers, caravans, snowmobile trailers, vans and light trucks under about 80 inches wide. The low-profile design fits tight spaces and the rugged build handles repeated water exposure common with launch ramps and winter road conditions.

• Suitable for boat trailers, utility trailers, caravans, and snowmobile trailers
• Works on trucks, vans and light towing vehicles under approximately 80 inches wide
• Low-profile shape fits recessed mounting pockets and open brackets
