1. Access the headlight assembly by removing the necessary cover or panel.
2. Disconnect the electrical connector from the bulb.
3. Remove the bulb from the socket by turning it counterclockwise.
4. Insert the new bulb into the socket, ensuring it is secure.
5. Reconnect the electrical connector.
Tools Required: None specific for bulb replacement.
Parts Required: New headlight bulbs (check specifications for correct type).

3. Clean Headlight Lenses

Sub-steps:
1. Use a headlight restoration kit or a mixture of baking soda and water.
2. Apply the cleaning solution to the headlight lens with a soft cloth or sponge.
3. Rinse with water and dry with a clean towel.
4. Optionally, apply a UV sealant to protect the lenses.
Tools Required: Soft cloth, sponge.
Parts Required: Headlight restoration kit or cleaning materials.

4. Inspect and Repair Wiring

Sub-steps:
1. Visually inspect the wiring harness and connectors for damage or corrosion.
2. Clean any corroded connectors with electrical contact cleaner.
3. Repair any damaged wires using heat shrink tubing or solder.
Tools Required: Electrical contact cleaner, soldering iron (if needed).
Parts Required: Heat shrink tubing or electrical wire (if repairs are needed).

5. Test Alternator and Battery

Sub-steps:
1. Reconnect the negative battery terminal.
