Additional Notes

The Kawasaki VN1700 Vulcan 1700 Vaquero uses the P21/5W bulb for its parking light across the 2011-2020 model years.
The P21/5W is a dual-filament bulb, with one filament rated at 21 watts and a second rated at 5 watts, allowing it to serve two distinct lighting functions within a single housing.
This bulb operates on a 12-volt electrical system, consistent with standard motorcycle electrical architecture.
The P21/5W uses a BAY15d bayonet base, which features two offset pins positioned at different heights to prevent incorrect insertion orientation during replacement.
The P21/5W is governed by ECE (Economic Commission for Europe) standards, meaning it is recognized and used across European and international markets rather than being specific to North American standards.
Because the BAY15d base is offset, it is not interchangeable with the similarly appearing BA15d base, which has pins at equal heights. Substituting an incorrect base type would result in a fitment failure.
