2002 Deville...Got in my car tonight and both my headlights are not working. High beams and parking lights work. Im assuming it is extremely rare to have both headlights blow at the same time. Any ideas?
It is rare but there's no law that says they should go at different time. There's also a possibility that you already had one bulb out but didn't notice it. If you have a replacement, you can just swap out and see what happens. Most likely they will work and you will need a new set of headlight bulbs.
I know that you resolved your issue with replacing the bulbs but I had the same problem and it was due to severe corrosion in the power distribution center under the hood on the driver's side. Many of the connectors to the various relays were almost turned into powder. For those with the same issue that replacing bulbs does not work, please read here
I had a similar problem, it was a very odd occurence. I had to change the bulbs, and then shortly after I changed the battery. Now my lights will randomly flash? Usually upon first 5 minutes of driving. These cars are odd. Thats for sure.
