is there any thing u have to do to your mustang when adding hid's

[gotgookie]

no you do not. hids use less power than regular lights so it doesnt make a difference. i read some cases that you need a relay of some sort, but mine did not have that issue.

Well minds did need a relay or transistors. to work. When the car is not running the lights work great, as soon as I turn the car on, the lights wheel just blink, then turn off. They would not stay on. And it all plug n play. no splicing of any wires.
