As can be seen from fig. 1, the light emitted from the second light source assembly can be adjusted in brightness after passing through the light guide lens 1, and the light shape in the low beam III region can be ensured not to be ultra-bright, which meets the requirements of regulations. Meanwhile, the light guide lens 1 can be lightened under the condition that the first light source component forms low-beam illumination, the effect of lightening the modeling of the high beam function area of the light guide lens 1 under the condition of low-beam illumination is achieved, and the requirement of lightening more modeling can be met while the illumination requirement is met.
