Additional Notes

The 1157 is the brake bulb size specified for the Polaris 800 RMK across all listed model years from 2000-2010, with the exception of 2006 and 2007, which are not present in the specifications.
The 1157 is a dual-filament bulb, meaning it carries two separate filaments within a single glass envelope, one rated at 21W and the other at 5W, allowing it to serve both stop and tail light functions from one unit.
The 1157 operates on a 12V electrical system, which is standard for powersports vehicles in this category.
The base type on the 1157 is a BAY15d bayonet mount, a two-pin offset design that prevents incorrect insertion by positioning the two pins at different heights along the base.
The 1157 conforms to ANSI standards recognized in both the United States and Canada, placing it within a regulated specification framework for bulb performance and physical form.
Because the BAY15d base uses offset pins, it is not interchangeable with single-pin bayonet bases such as the BA15s, even when the glass envelope size appears similar.
The dual-filament construction of the 1157 distinguishes it from single-filament alternatives like the 1156, which shares the same bayonet base family but lacks the second filament and is not a direct substitute in brake light applications requiring both functions.
