If you are looking for a switch that will fit in the hole used by Honda for the spotlights then here are the options I have found.
Remove the switch panel and unscrew the blanking plug from the plate, you should pull gently the trim from the fairing and the screws are under it for removing the switch panel.
A Narva illuminated Off/On Rocker switch will fit straight into the hole without modification, #62051BL (in amber) or 62053BL (Green), 62054BL (Red). Check out Narva's link here. Go to page 9 for this switch.
Alternatively, Jaycar have a smaller illuminated switch that can be fitted to the blanking plug.
Both switches are around the $4.00 price.
