Suzuki Motorcycle LT-A450X KingQuad AXi 4x4 uses HS1 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2007 to 2010 model 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 Suzuki Motorcycle LT-A450X KingQuad AXi 4x4 uses the HS1 bulb type for both its high beam and low beam headlight positions across the 2007-2010 model years.
The HS1 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments to serve both high and low beam functions within one housing.
The HS1 operates at 12 volts with a 35W/35W power rating, where each wattage figure corresponds to one of the two filaments.
The HS1 uses a PX43t base, which is a bayonet-style mount specific to motorcycle lighting applications and is not interchangeable with common automotive bulb 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 same HS1 specification applies to both the high beam and low beam positions, the vehicle uses a single bulb type to fulfill both functions rather than separate bulbs for each beam.
