The ground for the brake lamp. When the tail lights are off, the tail light circuit can act as a ground for the brake light. When the tail lights are on, it can't.

you need a new brake pressure differential switch
i am not sure you mean brake lights or tail lights.If brake lights don't work.You have to check out a brake light switch,(it conects to your brake pedal) make sure both wires are conected to the switch.And if tail lights don't work, you have to replace a head light switch.(where you turn your head light on and off)
Take a hammer to the tail lights then they will shut off but you might have to get them replaced or somting The tail lights you see may actually be the brake lights stuck on because of a faulty or out of adjustment brake light switch.
You have to pop the panels off inside of your hatch, right on the other side of the tail lights, you should be able to see the back of the tail light from there.
The head light switch is shorting out ,or a bad connection
It is possible the brake light switch is broken or out of adjustment and the lights you see in back are the brake lights stuck on.

With an ohmeter or a self-powered test light. Hook the two leads of your tester to the terminals on the brake light switch. Push down on the brake pedal and if the light stays off or the meter stays at infinity, the switch is bad.
open tail gate, pop the gray trim panel off rear hatch(dont worry they are held in with clips),twist and pull old light out, replace, push and twist, pop pane back on.
