Arctic Cat Alterra TRV 550 headlight bulbs utilize a 9008 size for both high beam and low beam applications. The replacement chart covers 2016 to 2017 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 9008 bulb is the sole bulb type specified for the Arctic Cat Alterra TRV 550, covering both the high beam and low beam headlight positions across the 2016-2017 model years.
The 9008 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 65W for high beam output and one rated at 55W for low beam output.
Because both the high beam and low beam positions share the same 9008 bulb, a single replacement unit serves both functions rather than requiring two distinct bulb types.
The 9008 operates on a 12V electrical system, which is standard for automotive and powersports applications in this class of vehicle.
The 9008 carries the P26t base designation, which refers to the physical connector type and pin configuration that must match the vehicle's socket for proper installation.
The 9008 conforms to ANSI standards as recognized in the United States and Canada, indicating the bulb meets defined performance and dimensional criteria within those markets.
