[0002] The high and low beams of car headlights adjust the illumination angle, enhancing the safety of nighttime driving, especially when turning or in different weather conditions, illuminating the road ahead in advance and reducing blind spots; at the same time, it can also reduce glare interference to oncoming drivers and improve the visibility of all road users; however, most current car headlights are integrated brackets; the high and low beams cannot achieve independent adaptive dimming.

[0003] The applicant discovered through a search that Chinese patent document with publication number 204037425U, published on December 24, 2014, discloses a manual dimming mechanism for automotive headlights. This mechanism connects the rear housing of the automotive headlight to a rearview mirror. The rearview mirror has a protrusion with an internal cavity, and a protrusion is also provided within the cavity of the protrusion. The dimming mechanism also includes a ball joint seat connected within the protrusion, and a ball head bolt connected within the ball joint seat. The ball head bolt is connected to the rear housing via a sealing joint. A release handle is provided along the direction of the rear housing on the ball head bolt, and the release handle is connected to the ball head bolt via a spherical limiting block. The ball joint seat includes a cup-shaped head, a toothed body, and a grooved bottom. The ball head bolt is connected inside the cup-shaped head, and a limiting ring is connected inside the teeth near the middle of the toothed body, thereby limiting the stroke of the dimming mechanism.
