Nilight UTV/ATV Turn Signal Wiring Harness Kit — Horizontal Rocker Switch, 8 LED Signals, Waterproof

This compact, durable kit supplies amber and red LEDs, a three-position SPDT rocker switch, and a pre-assembled wiring harness designed for 12V vehicle systems. It’s built from metal and ABS plastic with waterproof LED housings, sealed connectors, and a collection of installation accessories so you can add clear, legally recognizable turn signaling to a Polaris, Yamaha, Can-Am or many other off-road vehicles.

How does the horizontal rocker switch operate?

The included SPDT horizontal rocker switch provides three positions: left, center (off), and right. Tapping the switch to the right activates the amber LED signals; tapping it to the left activates the red LED signals. The center detent is the off position, preventing accidental activation during rides.

• Three positions: left (red), center (off), right (amber)
• Illuminated indicator to confirm active direction
• Compact horizontal form fits common dash panels
• Simple wiring with labeled connectors for straightforward hookup

What’s included and how does installation work?

Everything arrives pre-assembled to reduce installation time: a wiring harness with plugs, eight LED turn lamps, fuses, heat-shrink terminals, ring terminals, cable ties, and a printed instruction sheet. The harness is plug-and-play for most setups; if you plan to power all eight lamps independently, a few terminal splices are required as noted in the instructions.

• 1 wiring harness, 4 amber LEDs, 4 red LEDs
• 2 fuses, 16 heat-shrink terminals, 2 ring terminals
• 10 cable ties and full printed instructions
• Cut-and-reconnect step for full 8-light customization if needed

Will this kit work on my UTV, ATV, or golf cart?

The harness is compatible with a wide range of off-road and utility vehicles including Polaris RZR/Sportsman/Ranger, Yamaha Rhino/Viking, Kawasaki Teryx, Can-Am Commander, Honda Pioneer, Arctic Cat Wildcat, many golf carts, dune buggies and 4x4 projects. Confirm your vehicle’s 12V system and panel space for the horizontal switch before purchasing.

• Designed for 12V electrical systems — not for higher-voltage vehicles without converter
• Fits many major UTV/ATV and side-by-side models
• Check dash cutout size and switch location for a tidy install
• If vehicle voltage exceeds 12V, use a step-down converter to protect the kit

How does this kit perform in wet or dusty conditions?

LED housings and connectors are engineered for improved ingress protection; amber and red LEDs are chosen for visibility in rain and fog. Robust materials — metal mounting points and ABS switch casing — help the system withstand off-road environments when installed correctly.

• Sealed LED housings resist water and dirt
• Durable metal and ABS construction for long-term use
• Easy-to-replace fuses add electrical protection
• Cable ties and heat-shrink terminals provide secure routing and sealing

Who is this for: This Nilight turn signal wiring harness kit is aimed at UTV/ATV owners and DIY builders who want visible, reliable turn signaling without complex custom wiring. It’s a practical upgrade for weekend trail riders, utility vehicle owners who drive near traffic, and custom 4x4 or golf cart projects needing clear left/right indication. If you have a standard 12V electrical system, some basic tools and the ability to follow simple wiring instructions, this kit provides a straightforward way to add legal-style turn signaling to your off-road rig.
