XL40 LED Headlight Kit w/ Yamaha Shell - Yamaha YZ250FX/450FX ('19-20)

The Baja Designs XL40 Headlight Kit with Headlight Shell is a purpose-built LED lighting solution for Yamaha YZ250FX and YZ450FX riders who push into low-light conditions on tight singletrack, dual sport routes, and open desert terrain. Inspired by the performance of the XL80, the XL40 series brings serious trail lighting capability to dirt bikes running lower-output OEM stators, delivering a powerful beam without overtaxing your electrical system.

The included XL Trail Lens produces both a vertical and horizontal beam pattern that eliminates harsh hot spots and redistributes light across near-field and peripheral zones. That means smoother, more confident visibility through quick elevation changes, blind corners, and technical transitions where a narrow, concentrated beam would leave you guessing.

What sets this kit apart from a bare light purchase is the integration: the XL40 comes pre-installed inside a Yamaha-specific headlight shell, and the kit includes a wiring harness with switch and all necessary mounting hardware. There's no fabricating a mount or sourcing extra components — it connects directly to your bike for a clean, factory-looking install. If you ride after dark and want lighting that keeps pace with your skill level, the XL40 kit is a straightforward, high-performance upgrade.
