1. Faulty Bulb Indicator: The bulb indicator itself may be malfunctioning or experiencing an electrical issue, causing it to remain lit even when all bulbs are operational.
2. Incorrect Bulb Type: Ensure you have installed the correct type of bulbs for your Camry's headlights, taillights, brake lights, and other exterior lights. Using incorrect bulbs may trigger the bulb indicator.
3. Loose or Corroded Bulb Sockets: Inspect the bulb sockets for any loose connections or corrosion. Rusted or corroded bulb sockets can cause poor electrical contact, resulting in the indicator light staying on.
4. Wiring Issue: There may be a problem with the wiring harness connecting the bulbs to the vehicle's electrical system.
5. Multi-Function Switch Issue: On some Toyota models, a faulty multi-function switch (also known as the headlight switch) can lead to the bulb indicator light staying on.
To accurately determine the cause, it is recommended to have your vehicle inspected by a qualified mechanic or automotive electrician who can diagnose and fix the issue. They will be able to perform tests and identify the specific reason behind the illuminated bulb indicator.
