What exactly is an LED?
An LED is a solid-state, semiconductor device that has been specially designed to emit light. In fact, "LED" is an acronym meaning "Light Emitting Diode." At the heart of the LED is a tiny diode that generates light when a small electric current is applied.
What are the advantages of LEDs versus incandescent lights?
Unlike traditional, incandescent lights that use bulbs, LED lamps do not use delicate wire filaments that stretch, weaken and eventually fail.
When a vehicle’s brake lights are applied, LEDs respond instantaneously and provide a brighter, more focused illumination. Incandescent lights take about a quarter of a second to get to 90% full brightness.
A study by the University of Michigan’s Transportation Research Institute found that LED lamps respond on an average 2/10th of a second faster than standard incandescent lamps. Using test results at 65 mph, LEDs improved reaction time and decreased braking distance by 16 feet.
