I'm not really sure I understand your question, but I might be able to help anyway. This site has diagrams for infrared train detector circuits that can be made from Radio Shack components that are readily available. <br /> <br />http://www.mrollins.com/irled.html <br /> <br />The part numbers are even listed. There are also many other circuits there for making constant lighting, etc. <br /> <br />I hope you find this helpful. <br /> <br />Warren
