Hi there. Most of the time this is caused by a bad headlamp switch. When the switch fails, it will cause this to occur. If the switch is fine, then it may have an issue with the headlamp relay. I typically take my voltage meter and test the circuit starting at the headlamps until I find where the voltage is being lost.

If you want to have your headlamps fixed, consider having a certified mechanic, such as one from YourMechanic, come to your home or office to inspect the headlights and suggest any necessary repairs.
