The Arctic Cat DVX 250 headlight bulb uses an HS1 size for both high beam and low beam applications. The replacement chart covers 2006 to 2008 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 lighting positions for the Arctic Cat DVX 250, covering both high beam and low beam headlight functions for the 2006-2008 model years.
The HS1 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments, one for high beam output and one for low beam output, which accounts for its use in both headlight positions.
The HS1 operates at 12 volts with a 35W/35W power rating, where each wattage figure corresponds to one of the two filaments, both drawing equal power in this application.
The HS1 uses a PX43t base, a bayonet-style fitting with a specific pin configuration designed to ensure correct filament alignment within the headlight housing, as precise filament positioning directly affects beam pattern accuracy.
The HS1 is governed by ECE standards, a regulatory framework recognized across Europe and numerous other markets worldwide, distinguishing it from bulb types designed to North American standards such as the similar-looking H4.
Although the HS1 and H4 share a dual-filament halogen design and comparable wattage, they are not interchangeable due to differences in base geometry and filament positioning; substituting one for the other would misalign the beam pattern relative to the reflector housing.
