I also fitted twin LED reversing/fog lights for similar cost. Thread here on the conversion for the valance mounted versions that use Hella lamps. Note the rear loom wiring on 2006 onward Classic models provides for twin rear lights for both fog and reverse with pre-wired three pin connectors each side.
