Circuit Performance Plug-n-Play Heavy Duty Headlight Wiring Harness

Circuit Performance ceramic heavy duty headlight wiring harnesses install in seconds to protect your factory wiring from costly damage from high-wattage aftermarket bulbs. Don’t settle for other “high-temp” plastic connectors, Circuit Performance harnesses are constructed of a unique ceramic material that is built to last.

High-Performance bulbs are a great way to improve light output, but they create additional heat that can damage your stock wiring. Don’t risk it!

Plug & Play installation means no modification is necessary to your vehicle – installation takes only seconds. Bulbs not included.

EZ Plug-n-Play

Super easy plug-n-play installation means no modification to the vehicle is required. Simply plug inline between your bulb and OE harness, similar to an extension cord.

30 Second installation

The harness can literally install in seconds. Plug it in and protect your stock wiring from the additional heat associated with high-wattage aftermarket headlight and foglight bulbs.

Heavy Duty 16GA Wire

Heavy duty 16GA wire is used to decrease resistance thus decreasing the heat from higher wattage aftermarket bulbs. Simply put, thicker wire = more electrons = better light output.
