What are the differences between regular lights and LED lights?

Regular lights (assuming you are referring to automotive applications here) are "incandescent" bulbs which have the following features...
Create light by "trying" to burn out the filament (no oxygen inside the bulb prevents the burnout from happening).
Get very hot (see burnout above).
Use lots of electricity for the amount of light produced.
are fragile (weakened by physical shock and vibration).
Inexpensive to replace.
Burn out (always).
LED (stands for Light Emitting Diode) lights have the following features... Low power consumption (consumes milli-amps instead of amps) for the amount of light produced. Runs cool to the touch, even if on for a very long time. Virtually impervious to physical shock and vibration (is a solid-state device) Much, much more expensive than regular bulbs and usually require replacement of entire lamp assembly if they fail.
Generally last much much longer than regular bulbs, they get dimmer with age instead of outright burning out. Will not tolerate a voltage spike (such as can come from jump starting vehicle or failure of a voltage regulator while lights on or even from arc welding directly on the vehicle) and can fail outright if exposed to one.
Hope this helps.

Which type of LED lights is popular for holiday usage?
There are many popular types of LED (Light Emitting Diode) lights for the holiday season. This includes LED icicle lights, white wire LED lights and regular LED lights.
Led Christmas lights vs regular Christmas lights?
LED Christmas Lights are lit by Light Emitting Diodes which produce very little heat compared to regular Christmas lights. Led's also last up to 50,000 hours and are 99% efficient for the environment.
What are the advantages of using LED Christmas lights over regular lights?
led uses less eletricy and will last for years
Differences between organic LED and LCD?
There are quite a number of differences between organic LED and LCD. Some of the differences include illumination which is better in LED, LED consumes less power and also has light emitting diodes as the main component among others.
What is the difference between led and halogen lights?
Halogen light glows and LED is dull.
Are led tail lights better than normal tail lights?
The only difference between LED lights and normal lights is that LED lights are much brighter and are a brighter white than normal lights. Some find the brighter lights better, while others find the lights too bright.
What is difference between regular household light bulbs and led bulbs?
LED light bulbs definitely are more energy efficient than regularly normal light bulbs. Depending on the usage, LED lights can also last maybe twice or three times as much as regular bulbs. LED ones are better.
What are the differences between Plasma, HD, and LED tvs?
Plasma tvs are flat panel systems that are used in large televison displays. HD or "High definition" tvs have a higher resolution which results in clear image quality. LED tvs use LED lights for back lighting.
Are Christmas lights led lights?
yes they are led lights
What is a Zafira Led brake light?
Zafira LED brake lights are brake lights that utilize LED lighting instead of regular bulbs. The information for this product says they are easy to install and the wire needed for the LED lamp is included. The price for a set of two is $160 to $165.
What is the differences between a fluroscent grow light and a led grow light?
LED grow lights have a longer useful life than fluorescent lights, as long as 15 years for some fixtures, and thus a lower "total cost of ownership." The total cost of ownership includes the cost to buy the light, use it, and replace expired bulbs. One manufacturer estimates that the total cost of owning an LED grow light over five years is about half the cost of a comparable fluorescent lights.
