This as an experiment. I will replace the blue light with a red one later. The components are simple, a short piece of fiber optic lens (I took it off the christmas tree) , a small lighting effect circuit (w/constant, fast and slow strobe) got it from a ‘promotional’ pen, the electrical wire was stripped from a cellphone earpiece and three small battery (bounded in electrical tape). Put them together and… …IT"S A LIIIIIIIIIIGHT!!!
Great use of inexpensive parts. Are you wanting to simulate a FRED or end of train flasher? Perhaps you could move the red light over, when you change it out, to be directly over the coupler? From my experience, that is where I have always seen them.
Do you have any idea how bright the red will be? That looks like great work, but I'd agree on moving it over to the center above the coupler.
As close to the bottom as you can get it. The prototype FREDs mount on top of the coupler and the lights end up a foot or so above that.
The FRED units all flash at about once per second. Another tidbit is that they only flash after dark. If you really want to go all the way, you could add a DCC decoder with sound to imitate the soft whistle that the air driven battery charger makes!
