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.  Some sellers offer DIY (Do-It-Yourself) LED Kits where the LED's and the current limiting resistor are included, however, soldering is required.  If you are able to do your own soldering, a DIY Kit would be a money-saving option for you, however, if you are unable to solder, or you don't have the time to solder the LED's yourself, then be sure to look for pre-wired 12 Volt LED's that are ready to be wired up to your vehicle.

Where can I purchase pre-wired 12 Volt LED's?
There are many sources to purchase 12 Volt LED's from on eBay.  We at DAV Electronics invite you to view our 12 Volt LED auctions.  We are proud to offer our LED's in ELEVEN COLOR CHOICES!  We provide you with high quality LED's by taking great care with our solder joints as well as providing two layers of protective heat shrink.  We also provide 6-inch wire leads, helping ease installation.  Plus we include mounting clips and full instructions with all of our LED's!  We also provide unlimited e-mail support for any questions you may have about the LED's or installation.

How do I install DAV Electronics 12 Volt LED's?
Installation consists of a two wire hook up...Just connect the red wire to any 12-16 volt DC positive voltage source and the black wire to ground.  You can hook them up to a switch to turn them on and off when you want, or wire them into your headlight wiring so they turn on when you turn your headlights on. 

How do I mount DAV Electronics 12 Volt LED's?
We currently have three mounting options, black nylon mounting clips, clear mounting caps, and chrome or black plastic mounting bezels. 

Black Nylon Mounting Clips:
The black nylon mounting clips can be mounted by drilling a 1/4 inch hole in any material up to 1/8 inch thick.   Press the clip into the hole and insert the LED up from behind. 

Clear Mounting Caps:
The clear lens caps can be mounted by drilling a 1/4 inch hole in any material up to 1/4 inch thick.  Press the cap into the hole and insert the LED up from behind.

Chrome or Black Plastic Mounting Bezels:
The chrome and black plastic mounting bezels can be mounted by drilling a 19/64 inch hole, in any material up to 1/4 inch thick.  Then feed the LED's wires through the top of the hole and secure the bezel with the supplied lock washer and nut. 

Additional Mounting Option:
We have had customers report use of glues and epoxies to mount our LED's.


*Our LED's are designed to operate at their optimal brightness with a positive DC voltage between 12 and 14 volts.
**Please check your local laws on the use of interior/exterior lighting before installation, as some states only permit the use of certain colored lights.
