This is a brand new, Saleen Convertible Light Bar Brake Light Automatic Shut-Off Switch. It is new in the baggy and comes with wiring instructions. It gets easily wired into the wiring harness for the convertible motor. It will automatically shut the brake light off on the light bar when the convertible top is up, but will allow it to work when the top is down. It works on 1987-2009 Mustangs. Price:$40.00, shipped. Thanks.
