The Husqvarna FE350 uses HS1 bulb size 6235B for both high beam and low beam headlight applications. The replacement chart covers 2014 through 2022 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 widely specified bulb type across the Husqvarna FE350 headlight data, appearing in both high beam and low beam positions for the 2015-2022 model years.
The HS1 is a dual-filament halogen bulb rated at 12V with a 35W/35W output, meaning both filaments draw equal wattage, and it uses a PX43t base with ECE certification for use in European and worldwide markets.
Because the HS1 serves both the high beam and low beam functions within a single bulb, the Husqvarna FE350 (2015-2022) relies on one unit to handle both lighting modes rather than separate bulbs for each position.
The 2014 Husqvarna FE350 uses the 6235B bulb in both the high beam and low beam positions, which differs from the HS1 used in all subsequent model years.
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 HS1.
The HS1 and 6235B are not interchangeable. The HS1 uses a PX43t bayonet-style base while the 6235B is a festoon type, meaning the two bulbs differ in both base configuration and filament design.
The regulatory standards governing each bulb type also differ. The HS1 falls under ECE regulations, while the 6235B is governed by ANSI standards, reflecting a distinction in the certification frameworks between the 2014 model year and those from 2015 onward.
