what’s the use?
is not just decoration, traveling during the day are more open to let people discover, play a role tips to improve driving safety.

Advantages:
· day some models running lights is very beautiful, the car has become a bright spot or a family-oriented design.
3
Error:
· Not All daytime running lights are LED light, daytime running lights some models conventional halogen light source.
· Some models daytime running lights can be turned on or off individually. After some models turn on headlights, daytime running lights brightness will be reduced.

Technical principle:
usuallyWe saw the headlights of the vehicle on the front row of high-brightness light small groups is not uncommon, its name is called daytime running lights, the English abbreviation is DRL (DaytimeRunningLight). Daytime running lights of the vehicle are more easily identified when the daytime running lamps, mounted in the front portion of the vehicle body.
This is not a lighting fixture, not to make the driver can see the road, but to allow the vehicle to travel during the day to let other road user identification, in order to achieve warning, it falls under the category of lights. Daytime running lights brightness to meet the basic requirements, penetrating strong, but not too bright, so as not to disturb others. Functionally speaking, daytime running lights and rear reflectors role is very similar to what we usually see. It is a real safety equipment. According to foreign investigative bodies analysis, open the headlights while driving, can reduce 12.4 percent of the vehicle accident, but also to reduce the risk of dying in a car accident 26.4 percent.
Some daytime running lights LED light source is used, a light emitting diode LED, it is a solid state semiconductor device. It consists of two semiconductor (P-type and N-type semiconductor) and an active intermediate layer. When it ends with a negative voltage, and electrons and holes begin to move (positively charged ions) combined to produce radiation, i.e., light directly into electricity.
It is not to be used as a filament halogen bulb, LED electro-optical power conversion close to 100 percentage, the percentage of the halogen bulb only 12 -18 percent energy is converted to light, the rest have been consumed energy . LED 35 significantly reduced the percentage of power, but also increases the battery life, and the LED lamp life of up to a maximum 8000-10000 hours, longer life than the halogen lamp, smaller power consumption.

· EU: 2011 must be installed in new vehicles from daytime running lights
In order to improve road safety, the provisions of the EU since 2011, all new vehicles in the EU must install daytime running lights (DaytimeRunningLight, referred to as DRL). Unlike ordinary daytime running lights near light, daytime running lights which is specifically designed, the energy consumption is only 15 percentage of beam light of the ordinary. Using LED technology daytime running lights, energy saving effect is further enhanced, the energy consumption is only 10 percentage of beam light of the ordinary. When a car engine start, daytime running lights are automatically turned on, and continue to increase the brightness caused by other road motor vehicles, non-motor vehicles and pedestrians attention. When the night comes, the driver manually open near the light, daytime running lights are automatically turned off.
those from EU countries have begun to explore the response of the provision point of view, the use of daytime running lights do to improve road safety and reduce traffic accidents has played a positive and effective role. Cars, trucks and buses and other vehicles in the daytime running lights installed, its visibility has improved significantly, thereby increasing traffic safety.
