You'll need more than that...I think the SRT Challenger comes with HID's factory. You'll need housings, ballasts, bulbs, etc. A good kit is about $300. A cheap kit is about $50-100. There's a reason they're cheaper.
Yeah I just don't want to install modern housings and change the look the of front of the vehicle. If I could find someone or a place that puts the HID system into a 7" round light I'd prolly use it.
I have glass housings now for the headlights that used H4 bulbs. I was going to just buy a cheap HID kit and install it.
