Headlight and Spot Light adjustment:
Park bike with headlight 25 feet from a wall or other vertical surface, on level ground.
With normal load on bike (rider) and the bike sitting straight, measure straight up from ground to center of headlight/spot lights. Transfer that measurement to the vertical surface or wall.
Turn on high beam, center of high intensity beam should be on vertical center line on wall, straight ahead of bike.
Switch to low beam, top of beam should touch vertical center line on wall.
Cover headlight, turn on spots.
Adjust each spot straight ahead with the top of the beam touching the vertical center line on the wall (same as low beam).
Some folks prefer to "spread" the spots by aiming each one slightly outward from straight ahead.
See CVOJOE's post for the socket for the spot lights. It's a 9/16" socket with a slot cut out for the wire (similar to a brake flare nut socket).

BTW - the secret to adjusting the spots without getting ticked off is to just slightly loosen the nut, just enough to allow you to move the light by tapping with the heel of your hand. If you loosen it too much, trying to hold it in position while tightening the nut can lead to foul language, thrown tools, etc.
