Im having some problems with my recently installed DDM tuning hid kit. I purchased the 55watt kit for the low beams on my 2015 Silverado HD. Install went normal as this is probably the 8th DDM kit ive installed over the years. Install was on Wednesday, Friday I noticed that one or the other bulbs either wouldnt fire or would shut off some time while driving. A quick turn off and on of the lights would bring them back. I then left and drove 10 hours mostly at night and never had a single problem with the lights at all during the trip. Got back in the truck Saturday night and I had nothing. No matter how many times i turned them on and off, nothing. Not even a flicker. Drove with my high beams on for about 30 mins and still had nothing. Just got done inspecting everything. First thing I went for was the fuse because Ive had problems with those before and it seemed fine. Replaced it just incase and nothing. Changed ground, nothing. Inspected the relay and ballasts and all connections and they are good as gold. Pulled the bulbs out and put the stock ones back in and they work just fine. But I did notice that on each of the HID bulbs, they look pretty dirty and smoky. Is it possible that they both shit the bed at the same time or is something else causing the issues? Im lost now. Heres a picture of one of the bulbs.

Yeah the diode was in the correct direction. My guess is during the day, in auto light control, you can not turn on the brights by pushing forward on the lever. Works perfectly at night time.

Just did the 10-18 mod to my 2015 Silverado 2500. My only issue I am having is that I cant turn my high beams on when I have the headlight switch to "AUTO." I have to turn automatic light control off in order to use my high beams. Is that normal or did I do something wrong?
