2001 Mazda Tribute lights draining battery?

Off and on, my interior lights on my automatic window controls stay on. Sometimes they are faint, other times they are bright. One week, they'll be on each day, the other week, they won't stay on. My emergency brake light sometimes stays on when I'm driving, even if the emergency brake is off. I believe this slowly drains the battery. I have had to have it recently jumped a few times, then I'm good to go for a week. Several service centers have "fixed" it and it's OK for a few months then it starts doing it again. Not sure if there's a button i'm pushing to keep these lights on (checked my manual and didn't see anything) or if my electrical system is slowly failing.
