Headlight wont turn on
both headlights turn on if the keys are in the ignition but the vehicle is off, once i start the
engine one of the headlights go out. also both of my brights wont work with the car on
Start with 2 new bulbs and while it is still apart use a test light to verify power and grounds. what wires do what, hi lo and ground. Is it ok with 2 new ones or is there a problem before plugging in, during the tests.
Both randomly started working fine the last time I started it but I'll run the tests anyways. Thank you for the help
Filaments that break could still make intermittent contact based on vibration, jarring or temp, so that can be a simple answer.
