Arctic Cat 350 headlight bulbs utilize HS1 size for both high beam and low beam functions. The replacement chart covers 2011 to 2012 vehicle production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The HS1 bulb is the sole bulb type specified for the Arctic Cat 350, serving both the high beam and low beam headlight positions across the 2011-2012 model years.
The HS1 is a dual-filament halogen bulb, meaning a single bulb unit contains separate filaments for both high and low beam functions 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, which is a bayonet-style fitting specific to this bulb type and is not interchangeable with standard automotive halogen bases such as H4 or H7.
The HS1 is governed by ECE (Economic Commission for Europe) standards, a regulatory framework recognized across Europe and numerous other markets worldwide.
Because the HS1 is a motorcycle-specific bulb type, it is distinct from passenger vehicle halogen standards, and substituting a non-HS1 bulb would result in a base incompatibility.
