2. Inspect battery terminals for corrosion and clean them if necessary.
3. Ensure that the connections are tight and secure.

3. Fuse Inspection

Sub-steps:
1. Locate the fuse box (usually under the dashboard or in the engine compartment).
2. Remove the fuses associated with the lighting system using a fuse puller.
3. Inspect each fuse for a broken filament; replace any blown fuses with ones of the same amperage.

4. Wiring and Ground Inspection

Sub-steps:
1. Visually inspect wiring harnesses leading to the lights for any signs of fraying or damage.
2. Check all ground connections associated with the lighting system for corrosion or looseness.
3. Clean and tighten any loose ground connections.
