Nilight Fog Light Wiring Harness Kit 16AWG for H11 H9 H8 – 5‑Pin Switch, Relay & 180W Protection

This wiring harness is built to simplify adding or replacing fog light wiring on cars, trucks and SUVs. It uses heavy-duty 16AWG cabling, a power relay and a SPST rocker switch with illuminated LEDs, and accepts a wide range of fog light bulb sockets (H11, H9, H8 and many 800-series variants). Everything needed to wire dual fog lamps up to a combined 180W load is included, plus two spare blade fuses and a wiring diagram to guide installation.

How will this harness fit my fog lights and vehicle?

The harness is compatible with many common fog lamp sockets—H11, H9, H8 and several 800-series types—so it matches directly to the bulb connector on most aftermarket and OEM lights. It’s designed for 12V systems; for 24V vehicles the relay should be changed to a 24V-rated unit.

• Socket compatibility: H11, H9, H8, 886, 889, 892 and similar types
• Works with dual light fixtures wired in parallel
• Replace relay if your vehicle uses 24V power
• Provides clear wiring diagram for installer reference

What protection and safety features are included?

Safety is handled by a power relay that prevents overloading and a blade fuse that interrupts current during short circuits or over-current events. The kit includes two spare fuses so you can replace a blown fuse quickly without delay.

• Built-in relay isolates the switch from high current
• Blade fuse protects the circuit during faults
• Includes two extra blade fuses for quick replacements
• Load rating up to 180W total to prevent overheating

How does the 5‑pin rocker switch operate and install?

The bundle contains a Nilight 5‑pin SPST rocker switch that toggles power on or off to the fog lights. The switch has two soft LEDs so it’s easy to locate in low light and its wiring follows standard automotive color codes for fast integration with your vehicle’s wiring harness.

• SPST design: simple on/off control
• Two built-in LEDs for visibility in the dark
• Standard connector and wiring for fast installation
• Mountable rocker format fits common dash cutouts

Can this harness power dual fog lights and how long is the wiring?

Yes—the harness provides two output leads so you can feed two separate fog lamps from a single power source, with a total supported load of 180W. The main harness extends 7.2 feet, allowing flexible routing from engine bay to bumper area or under-dash switch mounting.

• Two output connectors for dual light fixtures
• 7.2 ft extendable wiring length for versatile routing
• Supports combined light power up to 180W
• Included diagram shows suggested cable routing and hookups

Who is this for: This Nilight harness is intended for DIYers, mechanics, and vehicle owners adding or replacing fog lights who want a reliable, protected wiring solution compatible with popular H11/H9/H8 sockets. It’s especially suited for installations where a dedicated relay and illuminated dash switch are desired, while remaining accessible to installers with basic automotive wiring skills.
