09 White Diamond Slade, 05 Black CTS-V, 94 White Diamond STS
I haven't had time to research this yet, but last night after I replaced one of my burned out brake light bulbs, I had my wife come step on the brake pedal without the key in the ignition and nothing happened. Only when I had her put the key in and turn it to the "run" position did the brake lights activate. Anyone familiar with the circuit to know wheather or not this is normal? Seems to me this could present a hazardous situation if that's how it's designed.
