  • Wiring: 1x Morimoto MotoCycle Relay Harness (H4 / Single Output)
  • Warranty: 2 Years
  • 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 Single-Lamp 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. Light Up: Each harness will power one HID ballast and one high beam function (solenoid) from one input trigger. Perfect for retrofitting either a single bi-xenon (hi/lo) projector or HID bulb in your headlight. 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.

    Well made, a solid connection.
    Size: 6 Pairs / 12 pcs
    I liked them. They really lock down on the speaker wire to make a firm connection. They seem well made and are easy to install. My system sounds great.

    Works as intended
    Size: 12 Pairs / 24 pcs
    These banana plugs are quite easy to use, and securely connected my speaker cables to the receiver. They have a quality feel as well.

    Tips broke in the binding post
    Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs
    UPDATE: Two tips broke off when unplugging them from the binding post and are now lodged in. Inexcusable and an utterly poor product. Solid connection in the binding post with no wobble or wiggle. They require some force to insert into the binding post, but once they're in they remain snug. I also tried removing and reinserting a few times and the connection remained solid. I've used other plugs in the past that have a softer tip and easily deform after one or two insertions. These do not have that issue.
