My boss has a 2011 Dodge Challenger with the 6.4L 392 motor, he is looking to change the color of the factory HID bulbs to a purplish color and the fog lights too.  The color of the car is Green with Envy and has gave the car the name "The Hulk".  Can we just change the bulbs to the factory or do we need to replace the entire HID system?  The fog lights according to the replacement bulb guide call for the 9145 bulbs, but we pulled the bulbs and they arent the 9145, original bulb is a Philiphs Ge40 i think. We are wanting to know if anyone has worked with the HID's or the fog lights before. Also, he is wanting to switch the rear brake lights and park lights to L.E.D.'s anyone know of any company we can get these from.
