Your taillight is out and the car is defaulting to using the brake lamp bulb as a tail light. Check all your rear bulbs, I'd put money down that you have at least one tail light is out. Make sure you use good Osram bulbs with the silver/nickel base when you replace bulbs.

If this is just for the tail lights there should only be one element in the bulb lighting up when the tail lights are on. If both are lighting up you have a problem. It should only be a single element bulb in the tail lights too.

It will say on the bulb carrier for the tail light if it is soposed to have a dual or single element bulb in it. For a tail light it should only say 10W in the plastic by the bulb, usually the brake will say 21W. If a socket takes a dual element it would say something like 21/5w meaning that it needs a dual element bulb, one element is 21W and the other is 5W.
