Led lights

Tie a knot in the wire bigger than the hole, or

Fasten the LED to the inside of the house first, then drop the wire down the hole.

Well, all things IMHO, you could use double sided tape to mount the LED I believe. I think you might want to consider just what type of effect you are going for. One has to be careful where the light is placed or you could end up shining it right into a person's eyes as they move around and view the layout. Mounting the LED at the top of the building and aiming it down can eliminate or reduce the chance of that happening but that effect may not be just what you want. Maybe you want the lower level lighted and the second floor dark? There are a lot of options out there. You could look at Evans Designs, one of our sponsors, website and get some ideas of what lights are out there. You will need a diode in the feed to the LED. Some of Evans' units come with that prewired.

Thank you, I did not think of double sided tape. I will check out Evans. My old set used light bases and bulbs.

Consider how you want to light the building. You don't want to be looking through a window and see the bright LED.  I generally glue the LED wires in place and suspend the LED.

I saw an example in a magazine where a guy drilled a hole in the back of the building up high and where it wouldn't be seen. Then he mounted the led at the end of a short length of drinking straw and pushed the straw in, gluing it when he had the right length.

On eBay, weHonest sells strip LEDs with adhesive backing with 3 strips of LEDs on each wire. Four of these costs $5.99 I think. Hard to beat that.
