While it's generally safe to drive with your car lights on for an extended period of time, it's not recommended. Driving with your lights on can drain your car's battery faster, which may cause other issues down the line. Additionally, having your lights on during daylight hours can be distracting to other drivers and may increase the risk of accidents. If your car lights won't turn off automatically, it's best to get them fixed as soon as possible to avoid any potential safety hazards.
