XL40 LED Headlight Kit w/ Yamaha Shell - Yamaha YZ250FX/450FX ('16-18)

The Baja Designs XL40 Yamaha YZ250FX/450FX Headlight Kit with Shell is a purpose-built LED headlight assembly designed to give trail riders, dual-sport enthusiasts, and desert racers dependable illumination once the sun goes down. Built around the XL40's moto-specific engineering, this kit is sized and powered for dirt bikes running lower-output OEM stators, so you get a serious lighting upgrade without overwhelming your bike's electrical system.

The XL40 uses the signature XL Trail Lens pattern, which spreads light both vertically and horizontally to eliminate harsh center hot spots. That means cleaner visibility through tight singletrack, quick elevation changes, and blind corners — exactly the conditions where flat or inconsistent light gets riders into trouble.

This kit ships with the XL40 pre-installed inside a model-matched Yamaha headlight shell, so fitment is straightforward and installation doesn't require sourcing separate hardware or fabricating mounts. A wiring harness with switch is included, keeping the entire setup self-contained and ready to bolt on.

If you're a YZ250FX or YZ450FX rider looking to extend your riding window into low-light and night conditions without a complicated electrical overhaul, this is the headlight solution built specifically for your bike.
