The Can-Am DS 450 headlight bulb uses HS1 size for both high beam and low beam applications. The replacement chart covers vehicle production spanning 2009 to 2015 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 type is specified for both high beam and low beam headlight positions across all listed model years of the Can-Am DS 450, covering 2009-2015.
The HS1 is a dual-filament halogen bulb, meaning a single bulb unit contains separate filaments for both high and low beam functions within one housing.
HS1 bulbs are rated at 12 volts with a 35W/35W power draw, where each wattage figure corresponds to one of the two filaments.
The HS1 uses a PX43t base, which is a specific bayonet-style fitting associated with motorcycle and powersports lighting applications and is not interchangeable with common automotive base types such as H4 or H7.
The HS1 standard falls under ECE regulation, which is the lighting standard used across Europe and many other markets worldwide, as opposed to SAE standards used in North America.
Because both the high beam and low beam positions share the same HS1 specification, a single bulb type serves the full headlight assembly rather than requiring separate bulbs for each function.
