Additional Notes

The Ski-Doo GTX 600 uses the 1157 bulb for the brake light position across the 2005-2009 model years.
The 1157 is a dual-filament bulb, meaning it contains two separate filaments within a single glass envelope, one rated at 21W for the brake/stop function and one at 5W for the running light function.
The 1157 operates on a 12V electrical system, which is standard for powersports vehicles in this category.
The bulb uses a BAY15d bayonet base, a two-pin offset base design where the two pins are positioned at different heights to prevent incorrect insertion during installation.
The 1157 designation follows the ANSI standardization system used in the United States and Canada, meaning bulbs from different manufacturers carrying the 1157 designation share the same electrical and physical specifications.
Because the 1157 is a dual-filament type, it is not directly interchangeable with single-filament bayonet bulbs such as the 1156, despite sharing a similar base style. The 1156 uses a BAY15s base with pins at equal heights, which differs from the offset BAY15d base of the 1157.
