Additionally, a built-in shunt resistor eliminates transient current and keeps the LED from giving a false-positive indication.

The LED has a life of up to 100k hr and is available in a variety of colors including red, amber, blue, green, and white. Typical light output is 15 lm, comparable to the 120MB incandescent. The manufacturer, DDP Engineered LED Solutions in El Segundo, Calif., accepts orders that include multiple colors.
