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.

All these was combined in LED bulbs, made by Lumen. To read more about this brand and check all featured products, you can visit this page: Lumen Off-Road Light Bars, Day Running Lights & LED Bulbs at CARiD.com

What do you think about these LED bulbs?

Send me a set and I'll give a review.

Do you have any non altered photo'* that highlight the LED light dispersion patterns when used in incandescent fixtures? I only ask because I have tried LED'* in the past, but have never been satisfied with the results in running lights and tail/brake lights designed for incandescent.

Also what do you recommend as the best approach for the load difference when it comes to the turn signals?

Usually they replace the old style mechanical flasher with an electronic flasher. Big trucks use them because of the load difference when trailers are attached, and a lot of the newer trailers are now coming with LED lights.
