Nilight 7/8" Motorcycle Handlebar Switch Wiring Harness Kit — 16AWG Dual-Lead, Relay & Fuse Protection

Compact 7/8" handlebar switch harness by Nilight delivers a protected, dual-lead 16AWG wiring solution to control auxiliary lights on motorcycles, scooters, ATVs and other 12V vehicles.

This Nilight wiring harness kit is built to add a reliable on/off switch to your vehicle’s handlebar while keeping wiring tidy and safeguarded. It converts a standard 7/8" motorcycle handlebar switch into a plug-and-play circuit with a power relay, blade fuses and two light-output leads—making it easier to run two lighting fixtures up to a combined 180W. The harness arrives with connectors and a wiring diagram to speed installation and reduce guesswork.

How does this harness protect my vehicle’s electrical system?

The kit uses a power relay and blade fuse to isolate the switch from higher current draw, reducing heat at the handlebar and protecting wiring from overloads or shorts. If a fault occurs, the included fuses blow to prevent damage to wire runs and connected devices.

• Power relay separates control circuit from load for safer switching.
• Blade fuses provide replaceable over-current protection.
• 16AWG wiring balances flexibility with current capacity for accessories.
• Prewired connectors minimize soldering and wiring errors.

Which vehicles and lights are compatible with this 7/8" handlebar switch kit?

The harness is designed for most 7/8" (22mm) handlebars and works across many 12V platforms including motorcycles, scooters, ATVs, UTVs, snowmobiles, tractors and some trucks. It’s suitable for a variety of auxiliary lighting where combined power does not exceed 180W.

• Fits standard 7/8" handlebars commonly used on motorcycles and scooters.
• Suitable for LED driving lights, fog lights, work lights and taillights.
• Dual leads allow two lighting fixtures or light banks to be powered separately.
• Adapters and connectors included for straightforward hookups.

How simple is installation for a DIY rider?

Installation is intended for riders with basic electrical skills and common tools. The harness bundles the relay, fuses and connectors so you only need to tie into a power source, ground and the 7/8" switch terminals following the included wiring diagram.

• Includes a printed wiring diagram to guide connections step-by-step.
• Pre-crimped connectors and 16AWG wire reduce preparation time.
• Plug-and-play style leads for two lights shorten installation labor.
• Blade fuses are user-replaceable without disassembling wiring runs.

What are the kit contents and useful specs I should know?

Nilight supplies the core hardware needed to add and protect auxiliary lighting without hunting for separate relays, fuses or connectors. The 16AWG conductors strike a balance between flexibility and current capacity for most light accessory setups under the specified power limit.

• Kit includes: 1 wiring harness, 3 blade fuses, 4 connectors and 1 wiring diagram.
• Two light-output leads support a combined load under 180W.
• Designed for 12V electrical systems and 7/8" handlebar switches.
• Wire gauge: 16AWG for routing around handlebars and frames.

Who is this for: Riders and DIY mechanics who want a neat, safer way to add or control auxiliary lighting from a handlebar-mounted switch. It’s especially useful for those running dual lights or light banks on motorcycles, ATVs, UTVs, snowmobiles and utility vehicles who prefer a protected relay-and-fuse solution with clear installation guidance.
