Facts & Figures


Power Delivery: A relay harness is designed to deliver steady voltage to your HID ballasts directly from the bike's battery. Nobody likes a flickering headlight, so why risk it? Factory headlight outputs are really only designed to power a halogen light bub, not a HID ballast.

One of a Kind: The H4 Single-Lamp Motorcycle specific harness is the first truly high quality relay harness designed for retrofitting a single headlight motorcycle with xenon projectors. We're proud to offer it!

What's the Difference:The wire lengths are designed to be more ideal for the layout on a motorcycle. Unlike a normal harness, which is designed for a car's engine bay that has to be modified, this one should be ready to go out of the box.

Light Up: Each harness will power one HID ballast and one bi-xenon projector/bulb solenoid, perfect for a bi-xenon projector retrofit into a single headlight on your Motorcycle.

Don't Skimp: As an important part of a finished headlight upgrade, don't skimp out when it comes to your wiring. The long list of features on the Morimoto MotoCycle Relay harness is easily worth the small premium over the eBay $10 special.

Work of Art: Aside from being a technical masterpiece, it's also a work of art. With its braided TechFlex insulation and clear relays mounted on orange bases, it will surely look factory-fresh routed through your fairings.
