Could someone tell me how to hook up lighting to layout buildings ?? where can I purchase the parts and power supply I need thanks
The best power supply is an inexpensive power pack - like the old Bachmann packs - check e-Bay.

You can also buy inexpensive AC or DC "wallwarts" at online stores. Here is a Google search for lighted buildings:

You can get the lights here if you want. Just see what interests you.

LED domestic decorative lights offer lots of opportunities to be creative.
