What is an LED?
A light-emitting diode (LED) is a semiconductor device that uses solid-state electronics to create light.  An LED light source (or diode) consists of a layer of electron rich material separated by a junction, from a layer of electron deficient material.  Both sit on a semiconductor base.  Power applied in the junction excites the electrons, which in turn emit photons of light.  The color of the light depends on the chemical composition of the layers.

How are LED's modified to run off of 12 Volts?
LED's must be modified to run off of 12 Volts.  To accomplish this, a current limiting resistor is soldered to one of the LED leads.  Once the resistor is in place, you are ready to wire the LED up to your vehicle.

What are some uses for LED's?
Customize the interior and exterior of Cars, Trucks, SUV’s, RV's, Motor Homes, Motorcycles, ATV's, Snowmobiles, Golf Carts, Go-Karts, Computers…the possibilities are endless!  A unique and cheaper alternative to traditional neon tubes!!!

What are the benefits of LED's?
LED’s (Light Emitting Diodes) don't get hot like regular incandescent lamps. They also use considerably less power:  Only .02 AMPS per LED!!! (100 LED lights only draw 2 AMPS!!!)  So you can use more of them without fear of putting a strain on your electrical system.  LED's generate no heat and our LED's have a usage life of over 100,000 hours, or about 11 years of continuous operation!!!   

What is an MCD and How many MCD's are the LED's?
MCD (short for millicandelas) is a measure of the light output of an LED.   The higher the MCD rating, the brighter the LED.  Purple/UV LED's are measured in Ultraviolet output which does not reflect the visible light output.  Thus, the Purple/UV LED's appear to be less bright than other colors of the same MCD rating.

What to look out for when purchasing LED's:
-Of course, check the seller's feedback comments to see what other eBayers are saying about the seller.
-Be sure to check for the quality of the soldered area of the LED.
-Check to be sure the soldered area is covered in protective heat shrink.
-Check to see if the seller includes mounting clips with the LED's.
-Check the MCD rating of the LED.
-Check to see how many colors the seller offers and if they offer one to fit your application.
-Check to be sure you know what you are purchasing
