Recently i saw a video of a chevy caprice "one of the 90's model" that when you stepped on the brakes or used the blinker, the lights would sequentially blink outwards, "like the Mecury cougar i believe it is." I thought this was so cool and would be awesome to have. Does anyone know how to do this? I'm pretty sure you have to buy a kit or something "which costs like $130

." my car is an 83 so i dont know if its possible on and older model like mine.
