How to Fix / Troubleshooting

Safety: Disconnect power before changing bulbs.

  • Replace bulb: Install a new bulb of the correct type and wattage as specified by BFT (often LED or low-wattage incandescent).
  • Check socket: Inspect the lamp holder for corrosion or heat damage.
  • Verify settings: In the BFT menu, ensure the courtesy light time is not disabled.
  • Board fault: If a known-good bulb does not light and settings are correct, the light driver on the board may be faulty, requiring board replacement.
