Additional Notes

The Ski-Doo Renegade X uses the P21/5W bulb type for the brake light position across the 2011-2018 model years covered in these specifications.
The P21/5W is a dual-filament bulb, with one filament rated at 21 watts for the brake or stop function and a second filament rated at 5 watts for the tail or running light function.
This bulb operates on a 12-volt electrical system, which is standard for powersports and automotive lighting applications.
The P21/5W uses a BAY15d bayonet base, an offset twin-pin mount that physically prevents incorrect single-filament bulbs from being seated in the socket, as the two pins are positioned at different heights.
The P21/5W designation follows ECE (Economic Commission for Europe) standardization, meaning the bulb conforms to internationally recognized performance and construction requirements used across European and worldwide markets.
Because the BAY15d base is offset, it is not interchangeable with the BA15d base, which shares a similar appearance but features pins at equal heights and is associated with single-filament or non-offset dual-filament applications.
