Wiring Lights in Buildings???

[challenger3802]

Flashing LEDs are better for inside buildings as there is no chance of overheated parts coming into contact with your buildings. LEDs can be hooked up to their own DC power source (or batteries), with a resistor wired in series to one leg of the LED to limit the current through the LED. Lots of different colours are available including variations on white. If you're interested in electronics it's fairly easy to construct your own flashing unit, so that varying speeds of flashes can be modelled.

even though you can use AC for lights, it will probably be wise to use DC in this case since the bulb in the lighthouse is probably a flashing LED...chuck[:D]

There is normally an "Accessory DC" set of terminals on better powerpacks--try out the bulb on DC first and see if it works. AC only works with certain things...

I have always hooked mine up to AC power, without any problems. If you hooked them to DC power you could control the brightness of them.

I have a Cornerstone lighthouse I need to wire. It's the bulb that flashes on and off. Does that light need AC or DC power? The instructions don't say. Also for all the other lights of the buildings, do they require the same.
Thanks in advance.
