Cree LED Daytime Running Lights For Volvo S60 V60 2009 - 2013 , Led Drl For Cars
Quote:Types of Daytime Running Lights (DRLs)
Three main types of DRLs are currently in use around the world:
a) low-beam headlights that illuminate when the car is started ("immediate headlights").
b) dimmed high beam headlights - the voltage to the high-beam headlights is regulated so that they have greatly reduced intensity.
c) dedicated lights with a defined beam pattern and light intensity.
Increased intensity yellow turn signals have also been used for DRLs. These illuminate constantly until the turn signal control is activated and then they flash (Bergkvist 1998).
In each case the vehicle is usually wired so that the DRLs illuminate whenever the engine is running.
DRLs that do not utilise normal low-beam headlights must deactivate whenever normal headlights come on.
Lamps that use Light Emitting Diodes (LEDs) are now being fitted to commercial vehicles as rear and side marker lamps (Decker 2000). They are claimed to require much less power for the equivalent performance. However, with current technology, this is only true with coloured LEDs (there are inefficiencies in producing a white light from LEDs). As this technology develops, LEDs may be utilised to provide a more energy efficient type of DRL.

Advantages |
CREE Light source and Driving chip,high Lightness |
1. The brightness of the DRL will help drivers to react to the changes in the road conditions and thus reducing accident rate by 12.4% and death toll due to accident by 26.45%.
2. Enable other drivers to notice you in a shorter time frame.
3. Lifespan of LED are 30 times longer than normal halogen bulb.
4. Brighter compared to conventional fog lights.
5. DRL uses lower current and thus reduces emission.
6. WINAUTO DRL is recognized by ECE R87 regulatory.
