The bottom light on the taillight is malfunctioning. I believe it's the trailer light bulb (194). Anyhow, I can get the light to come on if I barely plug it in but it goes out if I touch it. Thinking it's a contact issue. Was going to bend out the copper dog ears. If this doesn't work, can the entire bottom plug be replaced?

 

those wedge style bulbs (194) are junk !!.. try to clean the sockets up good w/ some emery cloth and w/ no lights on (so u dont blow a fuse) u can bend those tabs (in the socket) in to make a better fit then go to your local parts/hardware store and get some electrical contact GREASE not cleaner and fill up the sockets and put some on the base of the lights and put back in should be all set.. works for me everytime.. (knock on wood)
