All front lights went out simultaneously while driving
Last night, my husband's 2007 GS350 experienced a problem. All the lights on the front end of the car went out - no running lights or headlights. I don't know if the same happened to the rear lights. I wish he had pulled over so we could have checked them. Instead he turned the lights off and back on a couple of times and after a short delay, all the lights started working again. He runs his lights on auto, so my thought was a bad sensor, but the daytime running lights didn't come on when the problem occurred, so we don't think it's a bad sensor. I've done some reading on the forums about this and everything from fuse to ballast to headlights have been mentioned as the problem. Seeing that all the lights on both side of the front end of the car went out at the same time, I'm not believing it's a bad headlight or ballast, but I'm not knowledgeable enough about the anatomy of this car to feel confident in that belief. I'm leaning towards thinking this could be a fuse issue. The hole in my fuse theory is that it seems odd that they would start working again after a couple off and on sequences.
Thanks for the help!

Ballasts can be ruled out as apparently, you assume the whole system shut down. It doesn't have a chance of being ballasts/bulbs, BUT I would say this would be an exception to it.
If I am wrong on my suggestion, someone here please correct me.... But I'd take a look at a relay for your headlights. I am sure there is a relay for it somewhere as this would definitely explain what's gone bad.
Either way, good luck and hope it doesn't happen while you're on the road!

I agree with your husband. I personally do not like to stop on the side of the road and especially at night. Try everything I could to get everyone home safe, than find the problem and KILL it. Safety first.
Super weird that all lights went out. I think the problem is the switch to turn the light ON/OFF. Goodluck finding the problem.
