How+they+are+used

==LEDs have been around since the 1960s, but weren't used widespread until sbout 15 years ago. Now, LEDs are used in the home, businesses, and for outdoor purposes. LEDs are most commonly found in lamps, flashlights, indoor night lighting, art lighting, porch and outdoor lighting, mp3 players, DVD players, computers, TVs, and headlights.
