Once you do it properly, you'll ask, why so simple and really stupid to get these things to work.
I had the same revelation incorporating dozens of LED's to a HO model train layout for our RR museum in town. As a volunteer.
Right now I could do it blind folded. I ordered really cheap LED's from the bay. Clear, frosted, colors, multi colors, and others I got.
And they all worked. Other volunteers thought I was Superman. Nothing could be further from the truth.
