The DRL is helpful to prevent cars from car crush by making vehicle conspicuous which means the DRL would be automatically on while the vehicle engine stating in order to be visualized at daytime. In other words, the car with DRL could be easily seen by other car drivers, pedestrians or animals on time so that a car crush could be easier to be avoid because of bad weather bad visual. Commonly, a DRL is built inside of a headlight which is also comprised of a low beam light, high beam light, direction light and DRL, however, the headlight with DRL is only installed in a new car. In case of installing a DRL in old car, a new headlight with DRL ought to be replaced, but it costs fortune and takes time. Normally, the light from DRL is used a shade to reflect the Light Emitting Diode (as known as LED) light firstly and then to project the light out. As result, the projecting light won't be well distributed which means the center of the light projection area would be brighter but other part of the light projection area is brighten less. Moreover, the projection light could be scattered or glared so as to effect other drivers' vision.
