I installed my HID kit about a month ago, I took my headlights apart and installed shields so not to blind the other drivers. They were working great no problems until the rain started. My one headlight fogs up but it goes away after having the light on for about 5 mins, but that is not the problem. Not that it rains and is all muggy the drivers side light only works when it wants to. I turned it on this morning and it lit up but I went to go drive it tonight and nothing. The ballast has power I can hear it running when I put my ear to it. Anything I should test/or look for, all the connections look fine. How do I test if the bulb is bad, thanks in advance.
