The incandescent bulbs haven't really developed that much in the 140 years they have existed, while the development rate of LEDs is very rapid, with LED performance being doubled every 36 months, a development rate that is similar to the fast pace of computer development. There is no doubt that the future of automotive lighting belongs to the LEDs. What is LED? LED is short for Light Emitting Diodes. This is a form of transistor, doped with a substrate that emits light when current is applied. The LEDs have a number of advantages over incandescent lighting that are very attractive for automotive use:

- They are very insensitive to vibrations
- They last for the life of the vehicle (does not apply to headlight LEDs yet)
- They can be baked into moisture proof casings to be installed in all kinds of harsh environments
- They light up much quicker than incandescent bulbs
- They are extremely compact
- They can be made to emit different colors
- They run cool
- They give more light per supplied watt than incandescent light bulbs.
