Additional Notes

The Ski-Doo GSX 600 uses the 1157 bulb for its tail light across the 2004-2015 model years.
The 1157 is an ANSI-standardized bulb type recognized across the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared by all compliant manufacturers.
This bulb operates on a dual-filament design, where one filament handles running light output at 5W and a second, brighter filament handles stop or signal output at 21W.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to ensure the bulb can only be seated in one rotational position, preventing filament misalignment.
The bulb is rated at 12 volts, consistent with the standard electrical system voltage found in most powersport vehicles.
Because the BAY15d base is a keyed fitment, substituting a single-filament bayonet bulb or one with a differently spaced pin configuration would result in incorrect installation or function.
