The reason the 35w HIDs flicker is because the car thinks the bulb is burnt out so it trys to stop the electrical flow to the lights. But only when not pulling straight off the battery. The factory puts a certain size alt in to run what was ordered with the car not many after market items such as after market stereo's or other things. The easiest way to fix the flicker is the flicker fixes you will find around eBay most likely. Most people when ordering a 2.7L Charger don't think about the alt because it is basically a fleet vehicle but if you were to order the premium stereo and uConnect then it will most likely have the 160 alt in it. I have a friend who just did the 300c conversion to his Magnum he has a 2.7 and had to put the relays on to fix the flicker from the factory HID lamps he has. The big reason they come on and then flicker is because the HIDs take around 80w to come on but then run at 35w so when the power consumption lessens the car thinks the bulb is out. A bigger alt would also solve the problem and also open you up to more possibilities I know someone who is selling 250 and 300 amp Alts right now the only issue with them is they are untested so he has some people interested but not many. He competes in Sound contests so he needs the bigger alt.
