The replacement switch stands are the way to go. The individual LEDs are a PITA to solder if you don't have those "helping hands." I have one O72 switch which had the original LED burn out, which I replaced several years ago. It burned out again a few months ago. I attempted to replace it again with a spare LED I had bought back then but since I'm a few years older I'm not as steady as I was then so it has not been replaced. The LEDs are $3.00, so the whole switch stand is a bargain at $6.50 when one doesn't have to do any of that fine wire soldering. John, I measured about .3 of volt of AC at the point that supplies the LED. Do you think that could be what's causing it to burn out?
