Sorry could have been more clear. When the ignition key is on, engine running or not, the brake lights are always on. I have checked the wiring from the brake switch and it all checks out. And I have a stock brake systems except for the brake light switch from Pantera electronics. Everything works perfect, before they shop replaces the brake booster and master cylinder. The brakes, calipers rebuilt and lines were all replaced last year. So everything in the system is new and stock.
