The Husqvarna TE125 uses HS1 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2015 to 2016 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 sole bulb type specified across all listed positions and years for the Husqvarna TE125, appearing in both the high beam and low beam headlight sockets for the 2015-2016 model years.
The HS1 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for two distinct light output levels within one housing.
The HS1 operates on a 12-volt electrical system and carries a 35W/35W power rating, with each wattage figure corresponding to one of the two filaments.
The HS1 uses a PX43t base, a bayonet-style fitting designed specifically for motorcycle headlight applications, which is not interchangeable with common automotive bulb bases such as H4.
The HS1 conforms to ECE (Economic Commission for Europe) standards, a regulatory framework recognized across Europe and numerous other markets worldwide.
Because the high beam and low beam sockets share the same HS1 specification on the Husqvarna TE125, a single bulb type serves both functions rather than requiring separate bulbs for each beam.
