I'm putting the HD turn signal lite relocator to tag bracket, on my 07 Street Bob. Everything going fairly smooth, got everything off the bike with little problems. But then assembling the new parts on a table I got the part where you have to pop the bulb socket out of the existing signal lite cup. The instructions say to "carefully" pry the socket out. It has a rubber ring around it's circumference wedged against inside of chrome cup. I have tried a thin screw driver, a razor knife edge, but I cannot get this thing to move. I have almost torn the rubber ring and I feel like I am getting ready to break the socket. Anybody know any tricks on this thing ? The socket has to come out because the wires have to be rerounted thru the hole that the cup mounts on.
