Gas Gas Pampera headlight bulbs utilize HS1 size for both high beam and low beam applications. The replacement chart covers 2007 to 2008 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 is the sole bulb type specified for the Gas Gas Pampera across all listed positions and years, covering both high beam and low beam headlight functions for the 2007-2008 model years.
The HS1 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for both high and low beam operation 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 motorcycle headlight applications and is not interchangeable with common automotive bulb bases such as H4, despite the H4 also being a dual-filament halogen type.
The HS1 is governed by ECE (Economic Commission for Europe) standards, giving it regulatory acceptance across Europe and numerous other markets worldwide.
Because the Gas Gas Pampera uses the HS1 for both the high beam and low beam positions, both functions draw from the same physical bulb, and a single filament failure affects only one beam mode while leaving the other operational.
