Happy Day-After Thanksgiving, everyone! (You know, that infamous Friday.)
Saw these signals today at the Sears Lemax display section, and bought two sets (four signals) to try. at $5.35/set. They work fine! The LED’s alternately blink on-off, and they look about right size-wise; about 4-in overall height. They operate on 3v,4.5 VDC and all I have to do now is add a train-present detector, of which I already have several of the IR type.
I imagine that these signals will be even cheaper after Christmas, probably around $3 at Sears and other stores if they have any left.
Just thought you might like to know . . .
