Additional Notes

The 1157 is the brake bulb size for the Polaris Turbo IQ across the 2011-2012 model years.
The 1157 is an ANSI-standardized bulb type recognized in both the United States and Canada, which reflects a North American fitment standard.
The 1157 operates on a 12-volt electrical system, consistent with standard automotive and powersports applications.
As a dual-filament bulb, the 1157 carries two separate wattage ratings: 21W for the high-intensity filament and 5W for the low-intensity filament, allowing it to serve both brake and running light functions within a single unit.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to ensure correct polarity orientation during installation, preventing the filaments from being connected in reverse.
