Car lighting systems is continuously evolving.
Although a little bit pricey, current vehicle manufacturers use them because of greater benefits. Headlight bulbs made out of LED lasts up to 100, 000 hours compared to Incandescent bulbs that last only for 1000 hours. The efficiency of this device correlates to low pressure sodium lights that turn into sodium vapor for ultimate illumination performance. It contains plastic lenses in some models that spread the light at a greater angle for visibility. The focus of the beam can be made three dimensional or depending on the different lighting designs needed.
The light output of car LED bulbs improves overall night driving experience. The amount of light projected into the road spreads over a larger surface enough to read road signs and spot potential hazards when driving. Compared to traditional light bulbs that create dinghy yellowish colors, LED lights come in diverse colors.
Colored headlight bulbs range from standard white and yellow to attention grabbing blue, purple, red and green. The science behind it relies on the increased color temperature in a Kelvin scale. Colors within the range of 2700K0-4100K create warm yellowish light, 4100K-500K generate white color whereas 7500K-10, 000K above make colorful variations.
As opposed to ordinary headlights and taillights, LED headlamp bulbs do not cause strain on the engine and car battery. While incandescent bulbs take few milliseconds to light, LED bulbs don't need to be preheated. It reaches full brightness on the very instant the car pedals are stepped on. This is called light speed within nanoseconds. Light speed on the very instant the engine is turned on reduces rear end collisions and traffic accidents at night.
Additionally the bulbs last long and they do not need constant changing. With a lifespan of 10 years, this eliminates routine changing of defective car bulbs. This also cuts down cost on replacement as compared to standard automotive bulbs. It is harder to damage because it is very durable. The majority of automobile investors today are focusing on changing the face of car industry through the use of LED. One of its believers is the Korean government which is interested to spend 150 billion worth of investments by the year 2012 for car LED bulbs.
