Additional Notes

The 1157 is an ANSI-standardized bulb used in both the United States and Canada. It operates on 12 volts and carries a dual-filament design rated at 21 watts for the primary filament and 5 watts for the secondary filament, making it suitable for combined stop and tail light functions within a single housing.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights on the base. This offset pin arrangement prevents incorrect insertion, as a single-filament bulb with a similarly sized base would not seat correctly in a BAY15d socket.
The Polaris Turbo SwitchBack (2008-2009) specifies the 1157 as the tail light bulb size for both model years covered in these specifications.
Because the 1157 is a dual-filament type, substituting it with a single-filament equivalent would result in the loss of one lighting function, as the socket is wired to address both filaments independently.
