Second, low beam lighting units or high beam lighting units often employ a lens segment design. When the low beam lighting unit is lighted, each lens segmentation area is in a lighting state, and meanwhile, in order to enable the whole car lamp appearance to show a good lighting effect, the high beam lighting unit can also be lighted simultaneously, if light rays emitted by the light source are very easy to be converged by the lens and form light spots with high brightness, the low beam type super-bright can be caused, and the requirements of low beam regulations are not met.

The existing auxiliary light needs to be provided with a lens module independently, the utilization rate of the internal space of the car light is not high, and the technical problem of small-sized design of the car light is not facilitated.

In summary, the present application aims to provide a vehicle lamp, which can optimize the problems of high coupling degree, poor flexibility, and crowded internal space caused by the installation of auxiliary light, which are caused by the existing integrated module, and difficult miniaturization.
