So far, as of April 8, 2010, I have made 5 signals that have both front and rear lights that do fully function. I can make a few more of those with what little I have left. I can probably make another 5 more signals during the next few days.
These are just camcorder shots, not with a digital camera, because I don't have one that takes macro zoom. Maybe I can get one someday...
Anyways, here's a page that has a few unsorted pictures of my 5 signals so far that I've made.

Notes: I don't have the resources right now to do side lights, although future plans do include them, if I can get some smaller wire.
Cantilevers are also planned, but my resources are very limited right now.
Clear LEDs are also planned for the future, but the above statement qualifies here.
I do have a few flasher units, but I've forgotten how to make them work. I'll have to remind myself how to do so over the next coming weeks, and if I can get something to do a small signal setup with 2 signals, I'll try to make a video with the signals, and with a bell audio (I wish now I had bells. These would work great with these models...

Also, each signal was mounted together with JB Weld. For those of us who take care of things properly, they'll last a long time. For those who are a bit careless, they may have a chance to fall apart.

I use both the JB Weld, and JB Kwik for the signals.
The Private Crossing signs on a few pictures are actually used on some California crossings. Those people who are from California will recognize these right off the bat.
I do use the 1 track sign because it looks cool IMO. I left one signal blank, deciding whether or not to use the 1 track sign.
Any other questions, ask away.
