I would appreciate any "do it yourself" techniques used to efficiently and cost effectively illuminate multiple layout buildings. Buildings such as Ameritowne, Korber, Downtown Deco, etc.
What types of components to light up multiple buildings in a downtown area? What types of lights? Are you wiring in resistors? How are they harnessed in the buildings? Are they running off track power? In blocks so several buildings can be turned "on" and others kept "dark"?
Any insights appreciated!!
