Additional Notes

The Ski-Doo Renegade Adrenaline uses the P21/5W bulb type for the tail light position across the 2011-2018 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 one at 5 watts, allowing it to serve two distinct lighting functions simultaneously.
The higher 21-watt filament typically handles the braking signal, while the lower 5-watt filament handles the running light function, both operating on a 12-volt circuit.
The P21/5W uses a BAY15d bayonet base, which is an offset twin-pin fitting. The two pins are positioned at different heights on the base, a design that prevents the bulb from being inserted in the wrong orientation.
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 carries pins at equal heights. Substituting a single-offset base bulb with an equal-pin variant would result in incorrect fitment.
