Please read this manual thoroughly before installation and use.
Setup and Installation
The SYLVANIA 3893 bulb is designed for easy installation as a direct replacement bulb in compatible automotive systems.

- Safety Precautions: Ensure the vehicle's ignition is off and the lighting system is cool before handling bulbs. Wear appropriate protective gloves to avoid transferring oils from your skin to the bulb glass, which can reduce bulb life.
- Removal of Old Bulb: Carefully remove the existing bulb from its socket. Refer to your vehicle's service manual for specific instructions on accessing and removing bulbs, as procedures vary by vehicle.
- Installation of New Bulb: Insert the new SYLVANIA 3893 bulb into the socket, ensuring it is seated firmly and correctly. Avoid forcing the bulb.
- Testing: After installation, turn on the vehicle's ignition and test the newly installed bulb to ensure proper function.

Maintenance
Minimal maintenance is required for the SYLVANIA 3893 bulb. However, periodic checks and timely replacement are recommended to ensure optimal vehicle lighting and safety.
- Regular Inspection: Periodically check all vehicle lights to ensure they are functioning correctly.
- Replacement Schedule: Automotive bulbs, including miniature bulbs, dim over time. For optimal performance and consistent light output, it is recommended to replace bulbs in pairs, even if only one has failed. This ensures balanced illumination.

Troubleshooting
If the SYLVANIA 3893 bulb does not function as expected after installation, consider the following:
- Bulb Not Lighting:
- Ensure the bulb is correctly seated in its socket. A loose connection can prevent illumination.
- Check the vehicle's fuse box for any blown fuses related to the lighting circuit. Replace if necessary.
- Verify that the vehicle's electrical system is providing power to the socket.
- If the bulb still does not light, the bulb itself may be faulty. Replace with a new, known-good bulb.
- Intermittent Lighting:
- This often indicates a loose connection in the socket or wiring. Re-seat the bulb or inspect wiring for damage.
- Dim or Weak Light:
- Bulbs naturally dim over time. Consider replacing both bulbs in a pair for optimal and balanced light output.
- Ensure the vehicle's charging system is functioning correctly, providing adequate voltage.
If issues persist, consult a qualified automotive technician.
