A kind of method and device for switching of car light high-low light, independently controlled low light source and high light source are respectively arranged to carry out illumination, when carrying out low light illumination, independently open low light source, form low light illumination light line.High light source light line is deflected by high light source deflection lens and is irradiated on main lens to reduce the dark area between low light source and high light source, when carrying out high light illumination, low light source and high light source are simultaneously opened, the light line emitted by low light source and the light line emitted by high light source are fused by main lens, form high light illumination light line and carry out illumination.The beneficial effects of the present application are: using high light deflection design, the problem of single-lens high-low light spot not coinciding can be effectively solved.It uses lens to deflect high light source, eliminates the influence of dark area as far as possible, so that low light source and high light source can be effectively fused.On this basis, high light source eliminates halo caused by light dispersion by refraction and light path shielding.
