Default Brake lights staying on/killing battery

Long story short, I suck at anything electrical, and I don't know where to begin on my trucks new problem.
Brake lights, both rear and the one on the cab, have been staying on at random. The battery died after being parked for two days on one occasion, and I had no idea why. 6 months later while I am abroad it started up again. My roommate made it stop by tapping on one of the brake lights. A few nights ago, the inside of my house starts lighting up red, go outside and my brake lights are flashing at random. Looking in the cab I found my trailer brakes flashing too. I unplugged them from the back of the consul, and have not seen it happen again, but hooking back up again has not started the flashing.
2001 Dodge Ram 2500, edge fuel saver, trailer brakes, after market brake lights installed by previous owner.

"it started up again" was a terrible sentence. The light flashing was noticed for the first time six months after the truck mysteriously not starting due to dead battery. This was about a month ago.

Not 100% familiar with your truck, but in general you can check the switch on the brake pedal, see if you can open it up and clean it with some contact cleaner, if its dirty it will look dirty when you spray electronics cleaner on it (or it will look dirty in general) the fact that the brake controller was flashing points me to the switch on the brake pedal. i would leave the brake controller unplugged though to eliminate that. if it doesn't happen again in a period that you are comfortable thinking its solved, plug in the brake controller and see if it happens again, if it does, replace the brake controller.

I agree with Dragon, if its not the switch at the pedal, it could be in your brake controller or in the wiring that is connected to. Check that everything in its connections is tight and not showing any bare wires.
