Suzuki Motorcycle LT-A750 KingQuad AXi uses HS1 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2008 to 2019 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 for the Suzuki Motorcycle LT-A750 KingQuad AXi across all listed model years, covering both the high beam and low beam headlight positions.
The HS1 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments, one serving the high beam function and one serving the low beam function.
The HS1 operates at 12 volts with a wattage rating of 35W per filament, giving it a 35W/35W output designation that reflects equal power draw across both filaments.
The HS1 uses a PX43t base, which is a bayonet-style mount specific to motorcycle headlight applications. This base type is not interchangeable with common automotive bulb bases such as H4, despite the H4 also being a dual-filament halogen bulb.
The HS1 is governed by ECE (Economic Commission for Europe) standards, a regulatory framework recognized across Europe and numerous other markets worldwide, which defines its photometric and safety requirements.
The HS1 specification applies uniformly to the 2008-2009 and 2011-2019 model years of the LT-A750 KingQuad AXi, with no variation in bulb type between those years for either beam position.
Because both the high beam and low beam positions share the same HS1 specification, the vehicle uses a single bulb per headlight assembly to fulfill both lighting functions rather than separate bulbs for each beam.
