Way to state the obvious!!! ;) Just kidding, the brake light bulb is probably too short in the connector, my friend heifetz17 has the same problem with his license plate light. Either that or the connection just loosened up. Good luck.

You could have someone check to see if a light is in fact out. Or you could re-install the light bulb and holder into the tail light to see if it was a connection. Also check your contact points on the bulb holder assembly to see if they need to be cleaned up- give it a little action with a wire brush or steel wool

Go ahead and try checking for bad bulbs or loose connections and clean your contact points. If that doesn't work, just replace all the bulbs and it should go away. For some reason a perfectly good bulb can sometimes cause an intermittant failure message. I don't understand why it happens and I don't like throwing away perfectly functional bulbs, but replacing all the bulbs was the only thing that fixed it for me.
