PRR And Amtrak's Northeast Corridor Signals

I will need about HO scale 24 PRR amber signal disk and oval heads + 24 color signal disk and oval heads. 24 of these PRR signal heads will be color LED’s to simulate Amtrak’s North East Corridor. Another 24 PRR signal heads will be amber. All together I do know that I will need 12 amber PRR disks + 12 oval heads = 24 amber signals. 12 color PRR disks + 12 oval heads = 24 color signals. 24 amber disk and oval signal heads + 24 color disk and oval heads = 48. 7 lights in one PRR disk or oval = 7X48 = 336 LED’s!!! What size LED’s will I need to fit inside the holes of the signal heads. I am looking for pre wired 12v LED’s. I don’t know exactly how the colors are arranged on the signal heads. I do know that there are 7 lights on each signal heads, but for each signal head how many reds yellows and greens do I need for one PRR signal head which has 7 lights. Will I really need 336 LED’s or is there another way around. I really need help with this. I need all the help that I can get. I will be using these with my Digitrax SE8C.

If you’re talking about PRR position-light signals, all the lamps are amber/yellow. There are no coloured lights in this system.

Since you say you’re not sure what colours there are and how they’re arranged, it sounds like you may not really have any knowledge of the actual specific indications, which you would probably do well to find a PRR signal chart/rule book and study them in detail so that you can actually build proper signals and have some actual signal indications displayed, instead of random pretty lights that have absolutely no meaning.

Good luck finding prewired leds. Oregon rail supply makes scale PRR signal heads. Go to the PRR technical and historical society webpage andcheck the Keystone modelers there for a series on building PRR signalsby Jack Consoli.

Did you not already ask this question back in December?
