LED stands for Light Emitting Diode. They are designed to last for years and come in mostly green and red. However, you will find orange and blue ones as well. Where? Look on the front of your stove, microwave, TV, DVD, VCR, digital alarm clock, computer tower, power strip, modems, routers, cell phones, printers, electric tooth brushes. They are literally everywhere. At night my office looks like the Las Vegas Strip!...
