KTM 300 XC-W high beam and low beam headlight bulbs both use HS1 size bulbs, designated as 6235B. The replacement chart covers 2013 to 2020 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The HS1 is the most frequently specified bulb type across the KTM 300 XC-W headlight data, appearing in both high beam and low beam positions for the 2014-2020 model years.
The HS1 is a dual-filament halogen bulb operating at 12V with a 35W/35W output rating, meaning both filaments draw equal wattage, which is characteristic of motorcycle-specific halogen designs.
The HS1 uses a PX43t base, a bayonet-style mount defined under ECE standards and recognized across European and worldwide markets.
Because the HS1 serves both the high beam and low beam positions simultaneously through its dual-filament construction, a single bulb unit handles both lighting functions in the KTM 300 XC-W for 2014-2020.
The 2013 KTM 300 XC-W uses the 6235B bulb type for both high beam and low beam positions, which follows the ANSI standard used in the US and Canada rather than the ECE standard of the HS1.
The 6235B is a festoon-style bulb with blue tinted glass, a form factor that differs structurally from the bayonet-based HS1, making the two types non-interchangeable despite sharing a 12V operating voltage.
The differing standards between the HS1 (ECE) and the 6235B (ANSI) reflect a fitment distinction between the 2013 model year and the 2014-2020 range, and substituting one type for the other is not supported by the specifications.
