    my wife has a 08 GT that has some LED brake lights that stay partially on when the car is turned off. We’ve been having battery drain issues for a few months now and I noticed they were on but very dim when everything was turned off. Any idea what the problem could be? The lights still come on and off when the brake pedal is pressed. Thanks in advance for your help.

    What brand of lights? I'd go back to the incandescent lights for the time being.

    Some eBay brand that she liked and ordered. They’ve been on the car for 4-5 years with no issue. I’ll check out the wiring and see if I can find an issue somewhere.

    They’re not fully on though. It looks like the smaller lights are staying on but the larger ones that come on when I press in the brake pedal come on only when the I depress it. I’ll check for shorts.

    they do not have to be fully on for it to be a short. a fair number of shorts are incomplete, in other words they touch just enough to create a problem but not enough to fully engage the entire circuit.
