Kawasaki KAF620 Mule 4010 Trans 4x4 Headlight Bulb Size
The Kawasaki KAF620 Mule 4010 Trans 4x4 uses HS1 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2021 to 2022 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 listed across all positions and years in these specifications, covering both high beam and low beam headlight functions on the 2021-2022 Kawasaki KAF620 Mule 4010 Trans 4x4.
The HS1 is a dual-filament halogen bulb, meaning a single physical bulb 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 35W/35W power rating, where each wattage value corresponds to one of the two filaments.
The HS1 uses a PX43t base, which is a bayonet-style mount with a specific pin configuration. Bulbs with visually similar bases but different pin arrangements are not interchangeable with the HS1.
The HS1 is governed by the ECE standard, a regulatory framework recognized across Europe and numerous other markets worldwide, which defines its photometric and dimensional requirements.
Because the HS1 is a motorcycle-derived bulb type, it is distinct from the H4 bulb, which shares a dual-filament halogen design but uses a P43t base rather than the PX43t base found on the HS1. These two types are not interchangeable despite their similarities.
