You will have to focus on the circumstances and headlight conditions to know the cause. If you are a new driver, you might have difficulties getting to the bottom. Why do headlights fail? Here are the possible reasons for your help.

Issues with One Headlight

Dim Lighting

Your headlights might generate dim lights. It might be due to worn-out bulbs, foggy lenses, or problems in the charging system.
