Hi Ken!
So that's how they do it. I know they used only the one bulb. Brain half dead, didn't know how to word it. Just wanted to show the color changes as I remember talking about this before and some didn't know there were different colors.
Leds would be a cool way to do it though as Chryco mentioned...
Blown motor, I did hear that some did not say Slap Stik on the bezel, not sure why though. It should have a light. Sometimes the bulb goes out or falls out of place so I hear.
