In addition to good bed to frame grounds, you might consider a ground from each housing to the bed or frame. That's what I did on mine just to make sure there were no gremlins messing with the tail & brake lights. It may not fix the strange issue you're having, but who knows. You probably already checked, but make sure you have the correct (1157?) bulbs in each socket. Maybe also check the sockets to make sure they're clean and the contacts at the base are lined up correctly. Edit: I see REDROCKER already suggested the extra ground straps.
