Additional Notes

The Ski-Doo Tundra LT uses the P21/5W bulb for its tail light across the 2012-2019 model years.
The P21/5W is a dual-filament bulb, with one filament rated at 21 watts for braking or turn signal functions and a second filament rated at 5 watts for running light functions.
The bulb operates on a 12-volt electrical system, which is standard for this class of signalling bulb.
The P21/5W uses a BAY15d bayonet base, an offset two-pin fitting designed to prevent incorrect installation by ensuring the bulb can only be seated in one orientation.
The P21/5W designation follows ECE (Economic Commission for Europe) standards, meaning the bulb specification is recognized across European and international markets.
Because the BAY15d base is offset, it is not interchangeable with the BAY15s base used on single-filament bulbs of otherwise similar physical form, and substituting one for the other is not possible without modification.
