Solution
1. Preparation
  • Gather necessary tools and ensure the vehicle is parked on a level surface.
  • Disconnect the negative terminal of the battery to ensure safety during inspection and repair.
2. Inspect Headlight Bulbs
  • Remove the headlight assembly according to the manufacturer’s specifications.
  • Check the bulbs for damage; replace if necessary.
  • Ensure the bulbs are properly seated in the sockets.
3. Check Headlight Relay
  • Locate the fuse box and identify the headlight relay.
  • Remove the relay and test it with a multimeter; replace if it does not show continuity.
  • Reinsert the relay once verified to be functional.
4. Test Battery Voltage
  • Reconnect the battery terminal.
  • Use a multimeter to check the battery voltage; it should read between 12.4V and 12.6V when the engine is off.
  • If the voltage is low, consider charging or replacing the battery.
5. Inspect Wiring and Connections
  • Visually inspect the headlight wiring harness for any signs of wear, corrosion, or loose connections.
  • Clean any corroded connectors with electrical contact cleaner.
  • Secure any loose connections and replace damaged wiring as needed.
