Tail lights do not turn off and drained my battery.

Maybe water inside light compartment!

I don't know about cars

Check your brake light switch sounds like its stuck in the on position

sounds like the brake switch is not adjusted down far enough check it

tail light or BRAKE light ? if brake light replace the switch

Are you sure these are not the brake lights? I think they are. Go under the dash above the brake pedal and disconnect the brake light switch and see if the brake lights go off, if so replace the switch or adjust it.

you most likely have blown 10amp fuse for tail lights in the fuse box under the hood as far as tha tail lights go. turn your lights on and check your tail lights along with the plate lights. plate lights are on the same fuse as the tail lights. there is a fuse box by the battery which has tail light fuse in it. the lid of the fuse box is showing location of fuse. as far as your interior light goes, make sure that you have the switch in "door" position or it will not come on when door is opened. or just put it into "on" position to see if it comes on. but turn it off or put it back to "door" position/middle seting or your battery will drain down.

Are you sure it is the tail lights, or could it be the brake lights? If it is the tail lights, the light switch should be replaced. If it is the brake lights, there is a switch operated by the brake pedal whitch could be stuck or otherwise inoperative and should be replaced.

PUT TIMER IN TAIL LIGHT AND IT WILL OF ON THAT TIME WHEN U WISH :)

Since the only thing common to all four is the wiring in the steering collumn that would be the first place to look.
