You will need dual filament in rear. Front can be single or dual. Some existing wiring may be used and some wires will need to be added. Does the 54 turn signal donor switch assembly have wires hanging out? How many? What colors? Post a few pics of it. We will help you wire it no problem. It's fairly simple. Make sure the donor bell and switch fits OK. We can test the switch before you install. Need the questions answered and the pics. We all have the wiring diagrams. There are many.
I assume you have park lights up front? Are you 12V? You will need dual filament tail lights on both sides.
