Are the brake lights powered when the truck is off?

Hi guys! I've got an '07 Avalanche LT that I recently purchased. I put LEDs in the tail lights and could swear at that time the brake lights would come on when the brake was pushed, regardless of if the truck was on or not. I noticed yesterday that they now only work if the ignition is in "accessory" or "on". This includes the CHMSL. The park lights and hazard lights work fine when its off. Am I missing something or is this normal. I know its not a big deal, but I believe that if they are supposed to be working when the truck is off then possibly my BCM is going bad and who knows what else that could lead to.

Thanks everyone!
 
Could anyone that goes out to their truck check To see if their brake lights light up when the truck is off? I'd really appreciate it!

Thanks!
 
That is exactly how they behave on my 09. Also the same on my old 07 Tahoe.

Ok thanks! That makes me feel much better. Now I can go back to having fun with my new truck! ?
