Baja Designs 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. Backed by a 30-day satisfaction guarantee and Lifetime Limited Warranty.

See the XL40 Difference

All XL moto kits will now be available with a choice of either the XL40 or XL80 giving riders the ability to match the right light to their bike, stator output, and the terrain they ride. Watch our comparison video between the XL Pro and the new XL40 to see the improved light intensity and beam angle.

Paired with Trail Lens

Together, the XL40 and Trail Lens deliver enhanced nearfield and peripheral illumination for technical 1st–4th gear riding. The XL40 provides a smoother, more blended output when matched with the Trail Lens, which produces a balanced vertical and horizontal beam to improve visibility through rocky switchbacks, hill climbs, elevation changes, and tight technical turns.

More Compatibility

By re‑engineering the internals of the XL80 into a lower‑draw design, the XL40 works seamlessly with a wide range of motorcycles, especially those with smaller OEM stator outputs.  This means more bikes will be able to experience the Baja Designs difference.

High/Low Beam Functionality

The XL40 features both high and low beam functions, with the low beam dimming output by 25%. At full high beam, the XL40 provides 5,224 lumens, while low beam dims down to 1,435 lumens.
