The Polaris 550 INDY headlight bulb uses a 9008 size for both high beam and low beam applications. The replacement chart covers 2014 through 2019 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 Polaris 550 INDY uses the 9008 bulb type across both high beam and low beam headlight positions for the 2014-2019 model years.
The 9008 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both high and low beam functions within one housing.
The 9008 operates at 12 volts, with the high beam filament rated at 65 watts and the low beam filament rated at 55 watts.
The 9008 uses a P26t base, which is a prefocus-style base type that positions the filaments at a fixed point relative to the reflector for consistent light output.
The 9008 designation follows the ANSI standard applicable in the United States and Canada.
Because the same bulb size is specified for both the high beam and low beam positions, a single 9008 bulb serves both lighting functions in the 550 INDY headlight assembly.
