when I place a new bulb in my brake light sockets on my tail lights, my third brake light stops working and brake lights don't work at all either. Third brake light works fine if there are no bulbs in other two brake light sockets. As soon as I make contact with a bulb and the sockets, the third brake light goes out and starts working again if I take out the bulbs. All other tail lights are working. Not sure how to fix this.
