What are reasons for foglights not working besides blown bulb?

Besides a blown bulb, fog lights may not work due to a faulty switch or wiring issues, such as damaged connectors or corroded wires. A malfunctioning relay can also prevent the lights from operating. Additionally, issues with the vehicle's fuse box, such as a blown fuse specifically for the fog lights, could be the cause. Lastly, if the fog light alignment or mounting is incorrect, it may appear that they are not functioning properly.
