Customer Question

2007 LT silverado brake lights on all time with key on or running. Park LT relay pulled turns them off. Swap with starter relay makes no difference. Replaced brake switch a month ago and think everything was fine. Just noticed this last night.

I am very sorry for the long wait

will the 3 rd brake light also be on all the time ?

and the brake switch unplugged does the pink wire show 12 volts at it at the brake light switch connector ?

The cyclops light is on all the time as well. The pink wire has 12V on it, unplugged or plugged in.

if you jump the pink wire terminal in the brake light switch connector to the purple with the key ON will the rear side brake lights go out ?
