Over the summer I started to try my luck at making some LED lights for some of my locomotives. I used 0402 SMD led and magnet wire. These are in a Athearn RTR SD40. I also installed a ESU V5 decoder withh a Iphone 5 speaker. It took a bit of trial and earer to fit the speaker in the rear part of the shell. It sounds ok but next install I wont to try a speaker from Scale sounds.This is the LED after soldering the leads to it.

Here is the LED installed in the loco. I used Micro scale Krystal clear to seal the led in the shell. I have not touch any settings in the decoder and the leds are wired directly to the decoder.

I had a chance to work in the layout room the past couple of days so I got busy laying down some cork and some ties for the switches.
