Additional Notes

The Ski-Doo Renegade Sport uses the P21/5W bulb for its tail light across the 2010-2019 model years.
The P21/5W is a dual-filament bulb, meaning it contains two separate filaments within a single glass envelope, one rated at 21 watts and the other at 5 watts, allowing it to serve two distinct lighting functions simultaneously.
In tail light applications, the higher 21W filament typically handles the brake light function, while the lower 5W filament handles the running light function.
The P21/5W operates on a 12V electrical system, which is standard for powersport vehicles of this type.
The bulb uses a BAY15d bayonet base, a two-pin offset base design where the two pins are positioned at different heights to ensure the bulb can only be inserted in one orientation, preventing incorrect filament assignment.
The P21/5W designation follows ECE (Economic Commission for Europe) standards, meaning the bulb specification is recognized and regulated across European and worldwide markets.
Because the BAY15d base is offset, it is not interchangeable with the similarly sized BA15d base, which has pins at equal heights, despite the two bases appearing physically similar at a glance.
