LED lights as indicators in your vehicle

LED (light emitting diode) lights are fast becoming the light source of choice in many applications.  There are good reasons for this.  LED lights consume about 10th the power of an incandescent light bulb making them much more efficient.  LEDs also last much longer than incandescent light bulbs at approximately 100,000 hours.

In the vehicle, the LED is commonly used as an indicator for alerting you if a circuit is powered on, such as turn signals and high beams. They are also used as warning lights, such as low oil pressure and high water temperature.
