Good gravy!Mr Caveman et al are doing some cool things with LEDs.
Although I'm another one who doesn't subscribe to total changeouts (I reckon the light shows can get a little overwhelming/distracting if the LEDs aren't used judiciously) but of course it's all a matter of preference.
Beware, there is such a thing as LED poisoning . . .
Wish I had the coin to have trayloads of them on hand in those neato containers.
