The diagrams I've seen have the neutral (white) lead passing through
each switch box without ever going through a switch. Basically one
long neutral from the power source to the light without ever going
through a switch.
The hot (black) leads go into and out of each switch. Plus, an
extra hot (diagramed as red) between each switch. The last switch
provides the hot lead to the light.
You should be able to insert another light by breaking the long,
unswitched neutral lead and inserting your light at the break.
As someone pointed out, don't overload the switches ratings.
