LED (Light Emitting Diode, LED)
Compared with an incandescent bulb the LED consumes less electrical power and lasts longer, the LED has a burn time of up to 100 000 hours while a light bulb has about 1000 hours
Only 5 percent of the power pumped into the bulb comes out as light, the rest as heat.
LEDs, on the other hand, is rugged and shock-resistant, they are also up to 10 times as effective. Their lifespan is 50-100 times longer than incandescent and halogen and
LEDs can withstand temperatures from minus 40 to plus 100 degrees Celisus.
White LEDs emit a whiter light (6,000 K) than for example. ordinary light bulbs.
White LEDs can be combined with ex. Xenon headlamps to get the same color temperature of light.
Since LEDs require very little power to illuminate, then diodes on some cars (eg, 9-3 2003 -) with the bus system to flash when the car is "active" That car's system will send out small voltage pulses in the electrical system.
Normal incandescent light bulbs with the filament does not light of these pulses, which require more power to get them to shine. This will disappear when the car goes to sleep (after about 3 5 minutes)
