Gas Gas XC high beam and low beam headlight bulbs both utilize HS1 size bulbs for optimal illumination. The replacement chart covers 2011 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 bulb is the sole bulb type specified across all headlight positions in the Gas Gas XC for the 2011-2013 model years.
The HS1 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both high and low beam functions independently.
The HS1 operates at 12 volts and carries a 35W/35W wattage rating, with each value corresponding to one of the two filaments at equal output.
The HS1 uses a PX43t base, a bayonet-style fitting specific to this bulb type that is not interchangeable with other common automotive or motorcycle base types such as BA20d or H4.
The HS1 is governed by ECE standards, a regulatory framework recognized across Europe and numerous other markets worldwide, distinguishing it from DOT-regulated bulbs used in North American applications.
Because the Gas Gas XC shares the same HS1 specification for both the high beam and low beam positions across 2011-2013, a single bulb type fulfills both functions rather than requiring separate bulb sizes for each circuit.
