The Husqvarna TE511 uses HS1 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2012 to 2013 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 across all listed positions and years in these specifications, serving both the high beam and low beam headlight functions on the Husqvarna TE511.
The HS1 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for both high and low beam operation rather than requiring two individual bulbs.
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, which is a bayonet-style fitting specific to motorcycle headlight applications and is not interchangeable with common automotive bulb bases such as H4 or H7.
The HS1 conforms to ECE standards, a regulatory framework recognized across Europe and numerous other markets worldwide, governing output, beam pattern, and construction.
The 2012-2013 model years of the TE511 share identical HS1 fitment across both headlight positions, indicating no bulb specification change occurred between those two years.
