The present invention provides a vehicle lighting device wherein the lens arrangement includes an enhanced high-beam functional zone and at least two glare-free high-beam zones. By designing different projection angles for different zones of the lens arrangement, the light projected by several zones can partially overlap, and the combined light spot is therefore relatively uniform. In addition, the two adjacent glare-free high-beam sources are interconnected in the adjacent glare-free high-beam source groups, thereby shortening the wiring on the circuit board arrangement and allowing both light sources to be controlled simultaneously. By adding the low-beam auxiliary lighting function in each zone of the lens arrangement, i.e.,Adding the low beam auxiliary lighting light source groups to the circuit board assembly and adding the low beam auxiliary lighting reflector surface groups to the reflector shell assembly solves the problem of dark areas appearing in the lighting pattern when the vehicle's low beam function is activated but the high beam function is not.
