Upgrade your off-road lighting with the Baja Designs XL40 LED Headlight Kit — purpose-built for 2019–2020 Yamaha YZ250FX and YZ450FX motorcycles. Inspired by the performance of the XL80, the XL40 delivers 5,224 lumens of trail-proven illumination to a wider range of bikes. Engineered for dirt bikes with lower-output OEM stators, it draws just 43.5W — a powerful upgrade without the large power draw.

Paired with the signature XL Trail Lens, the XL40 produces both vertical and horizontal beam patterns with exceptional near-field and peripheral visibility. The Trail Lens redistributes center beam intensity to eliminate harsh hot spots — improving clarity through vertical transitions, quick elevation changes, and tight corners. The result is a smooth, evenly distributed field of light that inspires confidence in the most demanding terrain.

The XL40 comes pre-installed in a new Yamaha ’19–24 headlight shell with a wiring harness and switch for plug-and-play installation. Backed by a 30-day satisfaction guarantee and Lifetime Limited Warranty.
