When I tap on the brake pedal in my camaro with the engine and key off the dash lights come on along with the door chime and the front blinkers light up. I think it might be a ground issue somewhere. Any thoughts?

 

Could be an after market alarm system.Hope this helps.

 

I fixed the problem or problems. I did have an aftermarket alarm on the car, so I pulled out the fuses. I also cleaned the bulb sockets on the tail lights and replaced the bulbs with dielectric grease. I am not sure which one fixed the problem but my guess is it was the bulb sockets.
