The main technical requirements are consistent with ECE R79.

Below, we have a look to a qualified daytime running light products, which are the

Place is not free to change.

First, clearly defined standards, daytime running light color must be white,

Chromaticity characteristics must meet specified requirements.

White chromaticity coordinates:

Blue border: X ≥ 0.310

Yellow border: X ≤ 0.500

The green edge: y ≤0.150+0.640x

Y ≤0.440x

Purple boundary: y ≥0.050+0.750x

Red border: y ≥ 0.382

Secondly, a light-emitting surface area requirements shall not be less than 40cm2.

The most important point is that the light distribution performance, daytime running lights to meet the basic requirements of the brightness, but not too bright, so as not to interfere with others. Reflected in the technical parameter is a reference axis of the light emitting strength shall not be less than 400cd; the other direction on the luminous intensity should not be less than 400cd and light distribution map of corresponding points in percent product; in any orientation, lamp light intensity should not be greater than 800cd.
