Headlight bulb keeps going out.

I replaced my bulbs a months ago because one went out. I have a post on here about that. The low beam went out. Now it went out again. And I barely drive at night so I don’t know why this is happening. I don’t think the low beams are on during day.

I jsut leave the knob on auto

Both high beams still work

My next step was gonna be using a multimeter at the connector.

Yes, check voltage and wires for fraying. Some rigs use low beam for DRL but they shouldn’t go bad that quickly.

Make sure you don't touch the glass on the new bulbs when installing them or you will leave oil from your hands on it and it will cause it to overheat and burn out.

I would also check and clean your ground points for the headlight harness.
