All,

Looking for opinions and advice. I changed my HID bulb's and was working for a month or so until I received a fault code stating that my rear tail light was out; however the fault code went away and I thought the problem went away. A few days later now the headlight are not bright enough. I changed the level of the headlight to point higher. But that did not help the issue of dimming. I tried using the high beams and receiving the same brightness. Anybody ran into this issue?
