Additional Notes

The P21/5W is the brake bulb type specified for the Ski-Doo MX Z Blizzard across the 2016-2018 model years.
P21/5W is an ECE-regulated standard used in Europe and worldwide markets, distinguishing it from SAE-standard bulbs common in North American automotive applications.
The bulb operates on a 12V electrical system and carries a dual-wattage rating of 21W and 5W, corresponding to its two separate filaments.
The higher 21W filament serves the brake or turn signal function, while the lower 5W filament serves a secondary role such as a running or position light.
The BAY15d bayonet base features two offset pins at different heights, a design that prevents incorrect single-filament bulbs from being seated in the socket.
Because the BAY15d base is offset, it is not interchangeable with the BA15d base, which shares the same physical size but has pins at equal heights.
