I was pulled over after work and told I had a headlight out. I replaced both headlights and my drivers side still did not work. The high beams worked so I pulled one out while the car was running (which now I know was not good) and it flashed and now my drivers side high beam will not work either. Any answers?

Hello,

It sounds like you have a diode out. look at this wiring diagram to see if you see what I see. You can see one headlight runs through a diode. If you do not have DRL it will be an wiring issue. Here is a guide to help you find out:

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
