The Polaris Turbo SwitchBack uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2008 to 2009 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 9003 is the sole bulb type listed across all headlight positions for the Polaris Turbo SwitchBack, covering both the high beam and low beam functions for the 2008-2009 model years.
The 9003 is a dual-filament halogen bulb, meaning a single physical unit contains separate filaments for two distinct light output levels rather than requiring two separate bulbs.
The bulb operates on a 12-volt electrical system and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style fitting with a 43mm collar. This base type determines physical socket compatibility and is not interchangeable with other base configurations.
The 9003 designation follows the ANSI standard as used in the United States and Canada. It is functionally equivalent to the European H4 bulb, though labeling and packaging may differ by market.
Because the same 9003 bulb size is specified for both the high beam and low beam positions on the Polaris Turbo SwitchBack, a single replacement bulb type services both headlight functions.
