XL40 (D/C) LED Headlight Kit w/ Dimmer - KTM 150-300 XC-W; 350-500 XW-F; 450 XCF-W ('24-25)

Upgrade your off-road lighting with the Baja Designs XL40 LED Headlight Kit with Dimmer — built for KTM XC-W/XW-F/XCF-W motorcycles. Derived from the powerhouse XL80, the XL40 delivers 5,224 lumens of trail-proven illumination to a wider range of bikes. The The included dimmer lets riders dial in exactly the brightness they need, with a fully variable range from 95% down to 20% output.

Engineered for dirt bikes with lower-output OEM stators, the XL40 draws only 43.5W — making it the ideal high-performance upgrade for riders who previously lacked a compatible premium option. Paired with the signature XL Trail Lens, it delivers both vertical and horizontal beam coverage with excellent near-field and peripheral visibility. The Trail Lens redistributes center beam intensity to eliminate harsh hot spots — improving clarity through elevation changes, vertical transitions, and sharp corners. The result is a smooth, evenly distributed field of light that boosts confidence in demanding terrain.

This kit replaces the OEM headlight unit and includes a dimmer switch and Motominded mount for easy installation.
