The Husqvarna FE250 headlight bulb uses HS1 size designation, specifically the 6235B bulb for both high and low beam functions. The replacement chart covers 2014 to 2021 model 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 bulb type is the most widely used specification across the Husqvarna FE250 headlight data, appearing in both high beam and low beam positions for the 2015-2021 model years.
The HS1 is a dual-filament halogen bulb rated at 12V with a 35W/35W output, meaning both filaments draw equal wattage, which is a characteristic specific to motorcycle lighting applications rather than automotive ones.
The HS1 uses a PX43t base, a bayonet-style mount designed for motorcycle headlight housings, and it follows the ECE standard used in Europe and worldwide markets.
Because the HS1 serves both the high beam and low beam functions within a single bulb via its dual-filament design, the Husqvarna FE250 (2015-2021) relies on one bulb type to fulfill both lighting roles simultaneously.
The 2014 Husqvarna FE250 uses the 6235B bulb for both high beam and low beam positions, which differs from the HS1 used in subsequent years and represents a distinct fitment that is not interchangeable with the HS1.
The 6235B is a festoon-style bulb with blue tinted glass, rated at 12V, and follows the ANSI standard applicable to the US and Canadian markets, placing it in a different regulatory and physical category than the ECE-compliant HS1.
The physical and regulatory differences between the HS1 (PX43t bayonet base, ECE) and the 6235B (festoon, ANSI) mean that substituting one for the other across model years is not supported by the specifications.
