What type of device is needed for testing headlights?

The appropriate device for testing headlights is specifically designed to measure the aim and brightness of vehicle headlights, ensuring compliance with safety standards. This headlight testing device allows inspectors to check whether headlights are properly aligned to provide optimal visibility on the road and to avoid blinding other drivers.

Other tools mentioned serve different purposes; for instance, a brake lining gauge is used to measure the thickness of brake pads, a torque wrench ensures that bolts are tightened to the correct specifications, and a floor jack is utilized to lift the vehicle for maintenance or inspections underneath. These tools do not have the capability to assess the function or alignment of headlights, which is critical for vehicle safety.
