Important! : stereo cuts out when lights are put on

  1. #1
    right a finally thought i had sussed the wires for the stereo, put a cd in and everything worked fine.Went a drive and it started getting dark so put my lights on and the stereo cuts out! take my lights off and stereo comes back on!
    anyone had this problem?
    i dont have a clue what to do so any advice would be helpful?
