The Falco (and other V60 Aprilias) headlight control turns the dip beam off when the main beam is turned on.
This modification changes this functionality to keep the dip beam on when the main beam is on. For all types of headlights, this “fills-in” the light pattern in the short to medium distance when on main beam.
If you have upgraded to an HID dip beam it also eliminates the current surge every time you switch between main beam and dip beam.
The functionality is as shown:

History
This modification has previously been described by Tweaker and the French Aprilia V60 site (maybe others too). When I came to do this mod, I discovered that the Dip Beam switch on the newer Falcos has been changed – therefore this is an update to cover both switch types.
Open the light switch assembly on the left-side clip-on.
Old-style Switch:
For the older switch type, un-solder the black wire and re-solder to the centre connection point.
See pictures below:
Standard wiring

Modified wiring

New-style Switch
The newer switch looks like this when you get it apart:

Remove the plastic cover that hides the dip switch then pop the dip switch out.
Either unsolder the black wire (A) and re-solder it to the white wire (B) or solder a short piece of wire between A and B (I think this is easiest). Make sure you use a similar gauge wire to the other wires in the switch.
See picture below:

Put the switch assembly back together and your conversion is complete.
