Thank you everyone for your suggestions. I decided to put something together using a train transformer and stuff on hand. There is a resistor connected to the terminal strips. I can simply touch the LED wires to the spade connectors and test them quickly.
This is why I miss Radio Shack. Maybe I can buy a dollar store light string for the battery pack. And have more LEDs of course!
Thanks all.
Mark R.If they are white LEDs, I just use a couple AA batteries in series to test them. I have the batteries in a holder with test leads. Been using it for years to test LEDs. Mark.

Yep, have the same holder. (I think I got it @ Radio Shack years back.) Lay the battery leads across the LED leads briefly whenever I need to confirm if a stray or unknown LED is good or not.

Time...It marches on...without ever turning around to see if anyone is even keeping in step.
Thank you everyone! I won't get to them for a bit, on the table as a "when I get time" project but I appreciate the input.

I use a 9 volt battery with a 1K resistor.

A cheapo multimeter will put some light in a LED on its lowest resistance range. Mel My Model Railroad http://melvineperry.blogspot.com/ Bakersfield, California I'm beginning to realize that aging is not for wimps.
I have a string of LED Christmas lights that does not completely light. Is there a simple way of testing the LEDs? I can find plenty of uses for them on the layout.
