Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Headlights

Sub-steps:
1. Remove the headlight assembly using a socket set.
2. Examine the bulbs for any signs of damage. If damaged, replace with new bulbs of the same type.
3. Reinstall the headlight assembly and secure it properly.

3. Check Wiring and Connections

Sub-steps:
1. Inspect the headlight wiring harness for loose connectors and any visible damage.
2. Tighten any loose connections and repair frayed wires with electrical tape or replace as necessary.

4. Test the Battery and Alternator

Sub-steps:
1. Reconnect the battery and use a multimeter to measure the battery voltage; it should read around 12.6 volts when fully charged.
2. Start the engine and measure the voltage again; it should increase to about 13.7 to 14.7 volts if the alternator is functioning properly.

5. Final Assembly
