Husqvarna TE250 Headlight Bulb Size

Additional Notes

• The HS1 is the dominant bulb type across the Husqvarna TE250 headlight specifications, appearing in both high beam and low beam positions for the 2010, 2012, and 2015-2022 model years.
• The HS1 is a dual-filament halogen bulb operating at 12V with a 35W/35W output rating, built to the ECE standard used in Europe and worldwide markets. Its PX43t base is a bayonet-style fitting specific to motorcycle applications.
• Because the HS1 carries both a high beam and a low beam filament within a single bulb, it serves both lighting functions simultaneously in a single-bulb headlight housing, which is a common configuration in motorcycle design.
• The 2014 Husqvarna TE250 departs from the HS1 fitment, using the 6235B bulb in both the high beam and low beam positions.
• The 6235B is a festoon-style bulb with blue tinted glass, built to the ANSI standard applicable to the US and Canadian markets, and operates at 12V. Its festoon form factor differs structurally from the PX43t-based HS1, making the two types non-interchangeable.
• The physical and regulatory differences between the HS1 and the 6235B mean that bulbs from non-2014 model years are not compatible with the 2014 model, and vice versa, despite both types being 12V units.
• The HS1 designation is governed by ECE regulations, which define precise filament position tolerances to ensure consistent beam pattern alignment within the headlight housing. Substituting a non-HS1 bulb risks misaligned light projection.
• The 6235B is classified as a specialty application bulb, which generally indicates limited interchangeability with standard automotive or motorcycle bulb families outside its defined fitment.
