The automobile lamp inspection tool is a tool used to detect the installation state and matching accuracy of automobile lamps. It can simulate the state of the car lamp installed on the car body, and use the tool for size detection to directly or indirectly measure and evaluate the size relationship between the car body and the lamp (gap, surface difference). The lamp inspection tool is mainly composed of the main body and the auxiliary inspection tool. It needs to clearly reflect the basic information such as the datum plane in the height direction, depth direction and width direction, as well as the installation part of the lamp body and the body surface.
