What does L.E.D. stand for?

L.E.D. or LED stands for Light Emitting Diode.

Are these the same as HID (High Intensity Discharge)?

Although LED technology is similar HID technology, they are not the same. Sometimes you may see LEDs advertised at HID LED. Our Dragon LEDZ offer cutting edge advancement in lighting technology such as: Reduced glare, better contrast, extended lifespan, more controlled and natural beam pattern, more stable lighting and less power consumption and drain on your vehicle's electrical systems.

What is the main difference between LED and HID?

The main difference is LED technology is much newer, more advanced and more reliable (In most cases). LED technology is Solid State vs. HID which is xenon gas encapsulated inside a glass tube which wildly scatters emitting lighting into a light housing. Voltage dramatically fluctuates and is in most cases is very unstable ( Which in turn leads to voltage spikes and can do a lot of damage to your car and it's components but are not limited to frying all your wires, housing, and electronics). LEDs also do not use ballasts which have been proven time and time again fail on a regular basis. LEDs are also shock/vibration proof so you no longer have to deal with all the issues associated with HID failures. Cost of ownership is greatly reduced and will save you time, money and stress in the long run.
