The Introduction of LED Daytime Running Lights (LED DRLs)


    Our LED Daytime Running Lights (DRLs) is a kind of new-style green product for automotive. It is with RDW Emark-4 certificate. No pollution, no noises, no electronic interferer are its advantages. We adopted advanced constant-current controlling techniques for high quality.They are especially effective in preventing daytime head-on and front-corner collisions by increasing vehicle conspicuity and making it easier to detect approaching vehicles from farther away. Our product is greatly popular with our customers for equal price, high quality and good service.

   Suitable for almost every vehicle; 5 high-power led bulbs per lamp; Road legal in European Union; Newest digital brightness control; Heat protect circuit for ultra long last; Auto power on system, turning on with ignition;




2. Specification:

1).Product name:   LED Daytime Running Lights(LED DRLs)

2).Model:  D04   (1w/led bulb)

3).Certificate Name:   DRW  Emark-4

4).Whole kits Consist: Two LED lamps kits (Left one and right one), wiring, one gift box, user manual

5). Lamp Consist: Electronic circuit board, viewfinder, wiring, lamp hull and housing;

6). Electronic circuit board:

5 high-power LED and Controlling gearEmark approved

3.Major Technology Parameters of DRLS:

1).Rated Working voltage: DC 12V & 24V;

2).Rated Working current: 0.95A;

3).Rated Power consumption:11.4W;

4).Maximum surface temperature:≤50 Celsius degree

4. LED bulb technology parameters:

1).Bulb Color temperature range: 6,000K-7,000K;

2).Power: 1W each LED bulb;

3).Rated working current:≤350 Ma;

4).Current stablilty≤±2 mA;

5).Brightness is between 80 to 90 LM

5. Electronic Protection:

1). High-Voltage Protection:

The control system will stop working automatically to protect the control module from damage when the power voltage is higher than 15.5V, then LED light only works by the outer power directly;

2). Low-Voltage Protection:

The LED light will shut off to protect the system once the voltage is lower than 8v;

3). Lose-Frequency Protection:

The LED light shut off once the control frequency is abnormal to protect the control module and LED light.

4).Wrong-Connection Protection:

It is no harmful to circuit when the three cables of LED were connected incorrectly. The LED light is off when connection is incorrect, it will be on when connection is right. The three cables of LED light are VBB, Vss and VC respectively.

6. Other characters:

1). Anti-Vibration:

The Anti-vibration character of the LED DRL is accord with the requirements of the automotive relevant technical specifications.

2). Waterproof and corrosion-resistance:

The waterproof and corrosion-resistance of the LED DRL is accord with the requirements of the automotive relevant technical specifications.

3). Appearance:

The appearance of the LED DRL hasn’t obvious depression, rip, deformation. And it has clean and smooth surface without burr, light scratches, dirt, bubble, such as no more than 3 pcs. There are not obvious white granules inside the light housing and viewfinder.


The whole kits should include left LED light and right LED light, one cable assembly, two metal hasps for installing. All parts are placed into three inside small boxes with a manual installation.
