Back-up lights may not work due to several reasons, including burnt-out bulbs, a blown fuse, or a malfunctioning switch that activates the lights when the vehicle is in reverse. Additionally, issues with the wiring or connections could prevent the lights from receiving power. It's important to inspect these components to identify the specific cause of the problem. If troubleshooting doesn't resolve the issue, consulting a professional mechanic may be necessary.

During a power outage, some lights may still work if they are connected to a backup power source, such as a generator or a battery-powered system. These backup power sources provide electricity to keep certain lights functioning even when the main power supply is disrupted.
