The reproduction headlight sockets made in the last 10 years will work if they are installed properly. If your reproduction sockets are over 10 years old you need to get some new sockets. Most of the wiring harness sold today have the wrong terminal ends on them going to the headlights. Bratton's sells wiring harness with the correct terminals.
TO WORK CORRECTLY AND NOT SHORT OUT, YOUR TERMINALS MUST BE FLAT ON THE END AND THE CORRECT LENGTH.
The connector on the left shows the WRONG TERMINAL that most of the wiring harness come with, THESE WILL SHORT OUT because they are too long and not flat on the end. They will push too hard on the pins in the socket and cause them to slide off the terminal to the side and short out.
The connector on the right shows the correct terminals that are sold by Bratton's, you can install the correct terminals or file your old terminals to the correct length .687" or 11/16" and flat on the end as shown in the picture.
