Nilight 7/8" Motorcycle Handlebar Switch Wiring Harness Kit

Nilight's 7/8" motorcycle handlebar switch wiring harness is a ready-to-install 16AWG kit with two output leads, an inline relay and blade fuse to safely control auxiliary 12V–24V lights on handlebars.

This compact harness converts a standard 7/8" on/off rocker toggle into a protected lighting circuit suitable for motorcycles, ATVs, UTVs, scooters and other powersports vehicles. The kit includes a relay for load switching, three blade fuses, connectors and a wiring diagram so you can add or upgrade driving lights, LED bars, fog lamps or work lights without modifying the vehicle's factory wiring.

How does this harness keep my lights and vehicle safe?

The Nilight harness uses a dedicated power relay to handle high current while the handlebar switch controls the relay coil, not the full lamp current. A blade fuse sits on the power feed to prevent damage from shorts or over-current, and the 16AWG wiring balances flexibility and ampacity for common accessory loads.

• Integrated power relay reduces switch load and heat.
• Blade fuse (three included spares) protects the supply line.
• 16AWG leads for reliable current flow up to typical auxiliary loads.
• Two light outputs allow powering dual fixtures without extra switches.

Will it fit my 7/8" handlebars and the lights I already own?

The switch body is sized for standard 7/8" (22mm) handlebars and mounts like a typical motorcycle toggle. The two output leads accept most auxiliary lights under 180W combined, and included connectors simplify matching to common LED light bars and lamps.

• Standard 7/8" clamp fits most bikes, ATVs and scooters.
• Two separate light outputs for dual lamps or a single higher-watt setup (under 180W total).
• Includes multiple connectors to splice into existing lamp wiring.
• Wiring diagram included for straightforward installation guidance.

How easy is the installation and what’s in the box?

Installation is designed for DIY fitment with basic tools and a little wiring experience; the harness wires are labeled and a diagram shows each connection. The relay handles the heavy current, so only the low-current switch circuit needs to run to the handlebar, reducing the need to route thick power cable along the bars.

• Kit contents: wiring harness, three blade fuses, four connectors and a wiring diagram.
• Pre-terminated leads shorten installation time and reduce soldering/splicing.
• Low-current switch wiring runs to the handlebars for safer mounting.
• Compatible with 12V and 24V electrical systems commonly found in powersports vehicles.

Who this is for: Riders, home mechanics and fleet maintainers who want a reliable, protected way to add auxiliary lighting to motorcycles, ATVs, UTVs, scooters and small utility vehicles. Choose this Nilight harness if you want a plug-and-play style relay kit with dual outputs, spare fuses and clear wiring guidance that avoids heavy modifications to factory wiring.
