Can a car pass the annual inspection by installing fog lights if it doesn't have them originally?

If a car does not have fog lights, installing them can help it pass the annual inspection. A car without fog lights will fail the inspection, and if the fog lights are broken, it will also fail. During both the visual inspection and the on-road test, the lighting system is checked, and any malfunction will result in a failed inspection. The process of an annual car inspection includes: 1.
