my fog lights are 10kk. when i turn them on they fade in and stay on for about 5 seconds and then fade off. is it the ballasts? have they crapped the bed on me? i noticed a tiny bit of water in my fog light housings. could that have muffed up the bulbs? either way, it pisses me off, those things look awesome.
i had the same thing happen to mine and it was the ballast i dont know how long youve had yours but mine were still under wart.
