Nilight 16AWG Fog Light Wiring Harness Kit 5Pin Switch

Nilight's 16AWG fog light wiring harness kit is a ready-to-install 5-pin relay and rocker-switch system that powers up to two fog light fixtures (total ≤180W) and fits H11/H9/H8 compatible bulbs.

This kit bundles a durable 16AWG wiring loom, a 5-pin SPST rocker switch with built-in LEDs, a power relay, blade fuse protection, two light outputs and a wiring diagram to simplify fog light installs on 12V systems. It’s engineered for common fog lamp sockets and includes spare fuses so you can finish a clean, safe installation without hunting for parts.

What bulb sockets and voltages does this harness support?

The connector is compatible with a wide range of fog light sockets including H11, H9, H8 and related standards (886, 889, 892, PG13, PGJ13, 880, 862, 881, 884, 885, 894, 898, 899). The harness is designed for standard 12V vehicle electrical systems and handles a combined load up to 180W. If you plan to use a 24V system, replace the included 12V relay with a 24V-rated relay to match the vehicle voltage.

• Socket compatibility: H11/H9/H8 and listed variants
• Voltage: factory-configured for 12V; swap relay for 24V use
• Maximum load: up to 180W combined across outputs

How does the 5-pin rocker switch and relay improve safety and control?

The included 5-pin rocker switch uses an SPST design to provide simple on/off control while the power relay handles the heavy current so factory wiring and the dash circuit aren’t overloaded. The relay reduces voltage drop to the lights and the blade fuse protects the circuit against over-current or short circuits. The switch also has two soft LEDs so it’s easy to find in low light.

• SPST rocker switch for straightforward operation
• Power relay routes current through a robust contact, protecting vehicle wiring
• Blade fuse plus two spare fuses for circuit protection and quick replacement

What are the wiring length, outputs, and installation conveniences?

The harness includes approximately 7.2 feet of wiring, giving sufficient reach for most bumper-mounted fog lights and allowing tidy routing. Two output leads let you connect dual fog lamp fixtures without splicing extra connectors. A printed wiring diagram is provided to guide connections and reduce guesswork during installation.

• 7.2-foot extendable wiring for flexible routing
• Two separate light outputs for dual fixtures
• Supplied wiring diagram and extra blade fuses for easier install

Will this harness protect my lights and simplify maintenance?

Yes — the relay and fuse system are designed to protect against over-current events while keeping the high-current path off the factory switch circuit. The extra blade fuses included in the package make roadside fuse replacement straightforward. Wiring gauge and relay sizing help maintain stable voltage to the lamps for reliable illumination.

• Circuit protection via blade fuse and power relay
• 16AWG wiring for consistent power delivery to lights
• Extra fuses included for quick maintenance

Who is this for: The Nilight 16AWG Fog Light Wiring Harness Kit is intended for DIY installers, mechanics, and vehicle owners who want a compact, reliable solution to add or upgrade fog lights on cars, trucks, SUVs and off-road vehicles. It’s best suited for 12V systems using H11/H9/H8-style bulbs and for anyone who prefers a switch-and-relay setup with built-in LED switch illumination and fuse protection.
