Q: Why do I need a Circuit Performance Heavy Duty Harness?
A: Aftermarket upgrade halogen bulbs can create additional heat that can damage your factory headlight bulb harness. Circuit Performance Heavy Duty Wiring Harnesses are designed to install easily to protect your wiring from the additional heat generated by aftermarket upgrade bulbs.
Q: Do I have to modify my factory wiring?
A: No. Circuit Performance harnesses are a plug-n-play design which means the harness acts as a little extension cord and simply snaps in between your stock socket and the bulb. The harness can be installed or removed within seconds, great for leased vehicles!
Q: Do I need to replace all of my factory wiring?
A: No. The heat generated by high performance bulbs is isolated near the base of the bulb. Circuit Performance harnesses are made of a ceramic material that is designed to withstand that heat. As long as the rest of the vehicle's wiring is properly fused, no other upgrades should be necessary.
Q: My aftermarket bulb is stock wattage, would you still recommend upgrading the harness?
A: Yes! It's always a good idea to upgrade your harness when installing any aftermarket bulb, because whether you're turbocharging your motor, or improving light output, nothing is ever as safe as your stock equipment.
Q: Why should I choose Circuit Performance harnesses over another brand?
A: Circuit Performance
harnesses are made to a much higher quality standard than other
aftermarket harnesses. Circuit Performance uses a ceramic base that
plugs onto the bulb while other brands still use plastic. The ceramic
connector resists heat to a much higher temperature than any plastic
connector. Circuit Performance harnesses also use the
thickest gauge wire possible for each application (14GA in most
applications).
Q: Will this harness fit my vehicle?
A: Circuit Performance H10 Heavy Duty Harnesses will work in any vehicle where an H10 bulb is used.
