Power Delivery: The MotoCycle relay harness is designed to deliver steady voltage to your HID system directly from the bike's battery. Factory headlight outputs are really only designed to power a halogen light bulb and with the not-so-stable electrical systems on motorcycles - that could mean bad news for the longevity of your upgraded headlights without a harness.

One of a Kind: The Morimoto H4 Dual-Output Motorcycle specific harness is the first and only high-quality harness on the market that's designed for retrofitting HID's into the headlights on motorcycles. It's been a staple in our product line for years as the right go-to for the job.

In Comparison: To any other harness we offer, the MotoCycle spec's wire lengths are ideal for the layout on a motorcycle. It is not designed for a car's engine bay and has to be modified or rigged to work on a bike - this one should be ready to go out of the box. You can checkout this video to get an idea how it hooks up.

Light Up: Each harness will power two HID ballasts and two high beams from one input trigger. Perfect for retrofitting a pair of hi/lo Bi-xenon projectors or HIDs in your bike's two reflectors.

Work of Art: Aside from being a technical masterpiece that works like a charm, it's also a work of art. With its braided TechFlex insulation and sleek-looking black anodized relay - it will surely look factory-fresh when routed through your fairings.
