Smudge: Thanks, although I already knew about this store and have purchased from them.Try this guy, I've used him for the last 4 years for all my signal's lights etc. never had an issue. This is his UK but you'll find him on Fleabay in the US.

These guy's may be able to help with your IR detection as well.
The time period my railroad is in warrants the older 'search light' style signals for the most part, but is upgrading to 2/3 light signals and possibly some dwarf types. Most of the signal types Control Point point end are search light ( 2 heads one RGB each head ) and I have not found any at a reasonable cost. There are some frog end that are that too, unless the frog end happens to need an 'advance' signal, then two 3 lights on each mast on both tracks ( switch normal, switch reverse ). I don't even want to think about a signal bridge protecting 3 or 4 tracks going under it ... yet.
One of my pet peeve's is signal brightness and hue. In the case of brightness, if you are running at night with the run of the mill signals, you almost blind yourself looking at the things. The apparent brightness of the things can be changed. Hue is a whole nother can of worms. LED's from different manufactures have different color variations, in fact even the same manufacture can be different with different production runs. I figured that if I am going to roll my own, I may as well deal with both. So, all signal LED's need to be RGB's - with a search light you would need 5 wires ( 3 for color, 2 for multiplexing ), if 3 light signal - that would be 6 wires ( 3 for color, 3 for multiplexing ) running down the mast which could make those mast's fat. Add an advanced signal to that mast you now are looking at 9 wires ( 3 for color, 6 for multiplexing ). Am I going overboard? Maybe. Probably gonna be magnet wire to the rescue as most LED's are pretty bright running at 15mA. There is more to it for this, but that should give you and idea.
IR emitter/detector pairs are easy-peasy. Many moons ago I worked for a manufacture that made banking equipment that moved paper of which had to be location detected. Not a big deal all-in-all.
