Additional Notes

The Polaris 600 IQ uses the 1157 bulb for its brake light function across the 2009-2012 model years.
The 1157 is a dual-filament bulb, meaning it serves two brightness levels within a single unit. The higher-output filament operates at 21W for the brake or turn signal function, while the lower 5W filament handles the running light function.
The 1157 operates on a 12V electrical system and uses a BAY15d bayonet base. The BAY15d base features two offset pins, which physically prevents incorrect installation of single-filament bulbs that share a similar base style.
The 1157 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical parameters rather than being a proprietary specification.
Because the BAY15d base is offset, it is not interchangeable with the BA15d base, which also has two pins but positions them symmetrically. Substituting a BA15d bulb would result in incorrect fitment.
