Partsam Submersible LED Trailer Tail Light Kit — Square Tail Lights, 12" Light Bar & 25ft Harness, Waterproof IP67

Partsam's Submersible LED Trailer Tail Light Kit is a complete, waterproof lighting set that combines two square tail lights, a 12" light bar, eight side markers, reflective stickers and a 25-foot wiring harness for safe 12V trailer signaling.

This all-in-one kit supplies the essential exterior lights needed for small trailers, boat trailers and utility rigs where exposure to water, mud or rough weather is likely. Every component is built with sealed circuits and durable plastic lenses, so the lights keep working after splashes, launches or heavy rain. The package includes mounting hardware and a license plate bracket to simplify installation.

How well does this kit resist water and harsh conditions?

These lamps are engineered to meet submersible-use demands with a sealed circuit design and corrosion-resistant housings. The IP67-style protection means brief submersion or consistent wet conditions won’t short the LEDs or damage the board. That makes the kit especially suitable for boat trailers and coastal use.

• Sealed circuit board protects LEDs from water ingress
• ABS housing and PMMA/PC lenses resist impact and UV
• Designed for short-term submersion and heavy weather exposure

What components come in the box and how many LEDs are in each?

The kit includes two square tail lights, one 12-inch LED light bar, six amber and two red 2" side markers, reflective stickers, a plastic license bracket, gaskets, fasteners and a 25-foot two-piece wiring harness. LED counts vary by piece to balance brightness across functions like tail, stop and turn signals.

• Left square tail light: 19 LEDs; right square tail light: 15 LEDs
• 12" light bar: 15 SMD-style LEDs for center signaling
• Side markers: eight total (six amber, two red) with 3 SMD LEDs each

How is the wiring organized and what do the colored wires do?

The harness uses distinct color wiring so you can match vehicle signals to the light functions quickly. Each light has a ground line and separate wires for low (running/tail) and high (stop/turn) outputs. Follow the included wiring map to avoid cross-connection and test each function before final mounting.

• Square lights: white = ground; yellow/green = high brightness; brown = low brightness
• Light bar: white = ground; brown = tail/running (low); red = stop/turn (high)
• Side markers: black = ground; red = positive/power

Will this kit fit my trailer and how easy is installation?

The parts are designed for universal trailer fitment on 12V systems and include a 25-foot wiring harness split into long and short sections for flexible routing. Mounting hardware, gaskets and a license plate bracket are included so you can complete most installations with basic hand tools. For complex vehicle wiring or multiplexed systems, professional installation is recommended.

• Universal 12V compatibility for most trailers and boats
• 25ft total harness length (22ft + 4ft segments) for flexible placement
• Hardware and gaskets included to create water-resistant seals

Who this is for: This Partsam set is intended for trailer owners who need a durable, ready-made lighting solution—especially boaters, landscapers and weekend haulers who expose trailers to water or rough conditions. It's also suitable for anyone wanting an upgrade from incandescent bulbs to brighter, longer-lasting LEDs with straightforward wiring and complete mounting accessories.
