So I changed my fog lights out about 1 yr ago to hoen. I think. I notice 1 day that 1 was out. So I figured one just burned out. So I tap on the fog light lense and it came back on. I checked the wires connect to them and they look fine. I push on it to make sure the we're connected snug. The problem is both sides will go out. I just tap the lense and they come back on. Could there be ground connection on the light housing that's jack up. FYI these are then fog lights that matches the stock hids. That a member suggested
So it's his fault for my problem lol
