Nominal voltage: 12 V
Base type: BA15s (single-contact bayonet)

How to use
Switch off the vehicle ignition and ensure the circuit is not powered before replacing bulbs. Remove the lamp cover or housing according to the vehicle manufacturer’s instructions, press and twist the BA15s bulb to release it from the socket, and pull it out. Insert the new P21W BA15s bulb into the socket with a push-and-twist action until it locks in place, reassemble the housing and restore power to check correct operation. Replace bulbs in matched positions when required to ensure uniform light output across paired lamps.
Usage recommendations
Use these bulbs in fixtures designed for 12 V incandescent lamps and BA15s bases. Avoid touching the glass with bare hands on halogen or specialty lamps; for standard automotive incandescent bulbs, handle by the base where possible. Replace bulbs in pairs for symmetrical lighting on left and right sides, and verify correct polarity and socket compatibility before installation.
