Safety Information

Installation

Follow these steps to safely install your new replacement bulb:

  1. Prepare the Vehicle: Ensure the vehicle's ignition is off and the parking brake is engaged. For exterior lights, open the trunk or access panel to reach the light assembly.
  2. Disconnect Power: If possible, disconnect the vehicle's battery or remove the fuse for the specific lighting circuit to prevent accidental power surges.
  3. Access the Bulb: Carefully remove the light assembly or twist the bulb socket counter-clockwise to detach it from the housing.
  4. Remove Old Bulb: Gently push the old bulb inward and twist counter-clockwise to release it from the socket. If the bulb is hot, use gloves or allow it to cool.
  5. Install New Bulb: Holding the new Technical Precision bulb by its metal base (avoiding the glass), align the pins on the bulb's base with the slots in the socket. Push the bulb inward and twist clockwise until it locks securely into place.
  6. Reassemble: Reattach the bulb socket to the light housing, twisting clockwise until secure. Reinstall any removed light assemblies or access panels.
  7. Test Functionality: Reconnect the vehicle's battery or replace the fuse. Turn on the vehicle's ignition and test the light function to ensure the new bulb is working correctly.

Operation

Once properly installed, the Technical Precision 930F/1156-12V replacement bulbs will operate automatically as part of your vehicle's lighting system. For back-up lights, they will illuminate when the vehicle is shifted into reverse gear.

Maintenance

These bulbs are designed for long-lasting performance with minimal maintenance. However, periodic checks can help ensure optimal operation:

  • Visual Inspection: Periodically check the light output of your bulbs. If a bulb appears dim or flickers, it may be nearing the end of its lifespan.
  • Socket Connection: If a bulb is not illuminating, ensure it is securely seated in its socket. Loose connections can cause intermittent operation.
  • Cleanliness: Keep the exterior of your vehicle's light lenses clean to maximize light output.
