So I'd been on and off working on lighting on my layout, using mainly LEDs. But I wanted an effect of an era that was just moving from gas or oil lighting into electric. Around last Christmas the wife had some of those little battery operated tea lights set up as decoration. I was watching one flicker and thought this could be a possible solution.

Went to the dollar store and bought a pack on four and disassembled one. Not much to them, the switch on the bottom just pushes one of the LED legs against the little coin battery. So the flicker circuit is in the LED itself. Hmm.

So I installed the LED in the church on my layout and the effect is in the video below.

So then I started researching these on the internet and found they come in different sizes and ordered some 3mm ones on eBay. Also different colors of yellow and orange. Pic below, left one is from tea light.

So next I wanted to have gas street lights. I had some incandescent street lights I had from a box of stuff from an estate sale, I had acquired some time ago. You can change the bulbs in these just by popping the top off the lamp post. 

You can see in the next pic the LED is a little bigger than the bulb in the lamp. I was still able to install the led and use some fine wire wrap wire to solder tack on the LED leads and slide into the tubes on each side of the lamp. This is how power gets to the top.

My Depot on the layout had a lamp post that did not function. So off it came.

On with the modified lamp, after I painted it black.

And the lighting in action.
