Yamaha Headlight Wiring Harness w/Switch - Yamaha 14-18 YZ250F; 15-17 YZ250FX; 14-17 YZ450F; 16-17 YZ450FX

The Baja Designs Yamaha LED EFI Harness for the YZ450F is a purpose-built wiring solution that makes adding auxiliary LED lighting to your EFI-equipped dirt bike clean, straightforward, and reliable. Rather than splicing into existing wiring or cobbling together a generic harness, this kit gives you a plug-and-play connection designed specifically for the YZ platform's electrical system.

The included handlebar-mounted on/off switch puts light control exactly where you need it — at your fingertips, without taking your attention off the trail. Whether you're running an enduro stage that pushes into low light, doing a dual-sport conversion, or simply adding a forward light for early morning trail rides, this harness gives your build a factory-finished look and dependable function.

Designed for riders who take their bike builds seriously, this harness eliminates the guesswork of sourcing compatible wiring and worrying about voltage draw on a sensitive EFI system. It pairs directly with compatible Baja Designs lighting to create an integrated setup that holds up to the vibration, mud, and abuse that come with real off-road riding. If you're upgrading your YZ450F's lighting capability, this is the correct foundation to start with.
