The front parklights will have to be changed to dual lead sockets; the rear sockets are already dual filament and the "clamp on the column" kit takes that into account. You can also wire 4-way flashers through that signal kit, a nice safety feature to consider.

edit: Do you have one or two bulbs in your taillight housings?
