Why Choose OSRAM LEDriving® SL P21/5W Red?

Faded dual-filament incandescent brake and tail lights can run hot and degrade over time, slowing reaction times for drivers behind you. OSRAM LEDriving® SL P21/5W Red bulbs offer an instant performance and style boost, delivering faster light response and a vibrant red glow backed by trusted German LED technology.

• Fitment Note: Please check your vehicle’s manual or existing bulb socket (P21/5W / BAY15d bayonet base) to ensure correct compatibility before ordering. (Note: These products do not have ECE approval and must not be used on public roads in exterior applications).
