The Polaris 800 SwitchBack Assault 144 uses a 9008 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2011 through 2016 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 an ANSI-standardized halogen type recognized across the US and Canadian markets. It operates on a 12-volt system and uses a dual-filament design, with one filament rated at 65 watts and the other at 55 watts, allowing a single bulb to serve two distinct output levels.
The higher-wattage filament (65W) corresponds to high beam operation, while the lower-wattage filament (55W) handles low beam output. This arrangement is what makes the 9008 a dual-purpose bulb rather than a single-function unit.
The 9008 uses a P26t base, which is a prefocus-style single-contact base. This base type physically positions the filaments at a fixed point relative to the reflector, which is important for maintaining consistent light projection geometry.
The Polaris 800 SwitchBack Assault 144 uses the 9008 bulb for both the high beam and low beam headlight positions across the 2011-2016 model years, meaning both positions draw from the same bulb specification rather than requiring separate part numbers.
Because both headlight positions share the 9008 specification, the bulb's dual-filament construction is the functional reason a single part number covers what are otherwise two distinct lighting roles.
The 9008 designation is also cross-referenced as H13 in some international markets. These two designations refer to the same bulb construction, though fitment compatibility should be confirmed against the specific socket and housing before substitution.
