Well, I sent the deposit for the HID retrofits for my 2011 3500, I can't stand the factory lights. I honestly can't tell the difference between the low beams & high beams. I will pull the headlights out Thursday night, ship them to the retrofit guy on Friday. He should have them by Monday, will ship them back after the 2 or so day retrofit work, I should have them by next Thursday. He's installing new Infiniti FX45 headlights with Denso ballasts. I will reinstall the headlights, he's providing a harness that will connect to the original headlight plugs, I will run wires from the ballasts to the battery. Can't wait.
