My third brake light does not work on 2002 BMW 330xi

I bought a new brake light thinking the old one was no good. I installed the new light and it worked for one day only. the rest of the brake lights work just fine. Any ideas what it might be?

Is the new bulb burned out? Check the terminals and wiring to that one bulb if the bulb is OK.
