Additional Notes

The P21/5W is the brake bulb type specified for the Suzuki Motorcycle DR200S across the 2015-2019 model years.
P21/5W is an ECE-standard bulb recognized across European and worldwide markets, operating on a 12-volt electrical system with a dual-filament design rated at 21 watts and 5 watts respectively.
The dual-filament construction allows the higher 21W filament to serve as the brake or stop signal, while the lower 5W filament functions as a running or tail light within the same housing.
The P21/5W uses a BAY15d bayonet base, which is an offset twin-contact fitting. The offset pin arrangement is a deliberate anti-reversal feature, ensuring the bulb can only be seated in one orientation to prevent the filaments from being wired incorrectly.
Because the BAY15d base uses asymmetrically placed pins, it is not interchangeable with the BA15d base, which shares the same physical bayonet style but positions its pins symmetrically. Substituting a BA15d bulb in a BAY15d socket risks reversing the filament functions.
