2. Inspect and Replace Headlight Bulbs

Sub-steps:
1. Open the hood and locate the headlight assembly.
2. Remove the headlight bulb cover by unscrewing or unclipping it.
3. Carefully pull out the bulb and inspect it for any broken filaments or discoloration.
4. If damaged, replace the bulb with a new one, ensuring it matches the specifications.

3. Check and Repair Wiring and Connectors

Sub-steps:
1. Visually inspect the wiring harness leading to the headlights for wear, fraying, or corrosion.
2. Use a multimeter to test continuity in the wiring.
3. Clean any corroded connectors with electrical contact cleaner.
4. Secure any loose connections and replace damaged wiring if necessary.

4. Test Voltage Output

Sub-steps:
1. Reconnect the battery after repairs are made.
2. Use a multimeter to measure the voltage at the headlight connector while the headlights are on.
3. Voltage should be within the range specified in the vehicle's service manual (typically around 12-14 volts).
4. If voltage is inadequate, further investigate the battery and charging system.

5. Replace Headlight Relay (if necessary)
