I have Xentec HID's that I purchased from Joe on here. No problems so far. I'm running them in both my low and hi beams. If you go HID, contact Joe. I also purchased custom mounting brackets for them from Seth (Desertcat). I have some pictures posted somewhere. I'll try and find them and post them.
