Default Need help... Both low beams dead

Ok, so I'm driving down to zdayz right now in the middle of the night. My low beams were working perfectly fine for the past 500 miles, I pulled off the highway into a gas station, shut my car off, filled my tank, and then got back in to drive away. BUT when I got back I an turned my lows on, both beams were dead.

After doing some searching on my iPad, I checked all the fuses behind the battery, I even pulled out the low and high relays and checked those by swapping them. Same part, and the highs still work.

I then took out my tester, and turned on the lows and then the highs, and the tester shows there is current going to the relays.

After some reading I have heard some talk about the dimmer switch but if that was bad, then the relay would neither tick when the lights are turned to the on position or would there be power to coming through the test right?

I was wondering what the wiring mint be for the primary plug that plugs into the headlight, I could maybe check that to see if there is power going to the ballast.

I don't know what else it could be at this point, bad wiring? Bad ballasts? For both to go out at the exact same time leads me away from the lights themselves, but could the bulbs be blown from a surgeon enegery?

Any help would be appreciated, thanks in advance.

Have you ever taken the headlamps out? There is a master connection for all components within the headlamp. The power going to the ballast is a simple positive and negative connection. You could take two long leads and go from the ballast straight to your battery to see if they still work.

I can't imagine both ballasts just dying, there has to be some electrical issue within the harness or a switch. But the bulbs could be blown from some sort of surge as you suggested. Take a bulb out and look at it, if it is black inside the salts are toast and you need new bulbs.

I'm not sure what to tell you i'm not really good at electrical stuff. Good luck I hope its something not too crazy. You might browse hidplanet.com or theretrofitsource.com forums as they both have some experts who really know the whole headlamp wiring system in lots of cars.
