How to use
To replace the bulb, ensure the vehicle's ignition is turned off and the lighting circuit is deactivated. Access the light housing by removing the protective cover or lens as specified in your vehicle's owner manual. Gently push the old bulb into the socket, rotate it counter-clockwise to release it, and remove it. Insert the new Osram bulb into the socket, aligning the pins with the slots, push down, and rotate clockwise until it locks securely into place. Test the light before reattaching the housing cover.
What to consider before purchase
Verify that your vehicle's socket type is compatible with the BAY15D base.
Check your vehicle manual to ensure the 25W power rating matches your specific lighting requirements.
Confirm that your vehicle operates on a 12V electrical system.
Usage recommendations
Always replace bulbs in pairs to ensure consistent brightness and color temperature across both sides of the vehicle. Avoid touching the glass of the new bulb with bare fingers, as oils from your skin can cause hot spots and reduce the lifespan of the bulb.
