Wiring, relays and adapters for lighting installs.
Pick by what you are wiring:
- HID installs: relay harnesses for H4/9003, H7, H11/H9/H8/880/881, H13/9008 and 9005/9006/H10/9012, and Bi-Xenon hi/lo controllers for H4, H13, 9004 and 9007.
- LED fixes: 50W load resistors to stop hyper flash and dash warnings.
- Light bars and aux lights: relay harnesses with switch in single, dual and quad output, heavy duty light bar relays, and vehicle light bar kits with wiring.
- General 12V: 5-pin 40A and 4-pin 30A relays.
- Adapters: LED headlight adapter harness for 2014-2017 Harley Touring.
Harnesses are listed by bulb size, so match the size your headlight uses. Count your lights before picking a single, dual or quad output harness.

FAQ
What does an HID relay harness do?
It powers the ballasts straight from the battery through a relay, instead of from the factory headlight wire. It fixes flicker and no-start problems on many vehicles.
When do I need a load resistor?
When LED turn signals flash fast or the dash shows a bulb-out warning. The resistor adds back the load the car expects. It gets hot, so mount it on metal away from wires.
Single, dual or quad output harness?
Pick by how many lights you are wiring to one switch. One light bar takes single, a pair of pods takes dual, and four pods or a bar plus pods takes quad.
