Inspection Steps
The first step in troubleshooting headlight issues is to inspect the headlights visually. Check if both headlights are working and shining at the correct level. If one or both headlights are not working or are shining too low, there may be an issue with the bulbs, wiring, or electrical system.

Common Fixes

Suppose you suspect that your car is facing an alternator issue. In that case, it’s best to take it to a mechanic for a professional diagnosis.
In conclusion, if you see the “Check Headlight Low” warning on your car’s dashboard, there may be an issue with your headlight system. Follow the inspection steps and common fixes outlined above to troubleshoot and fix the problem.
