Why does the headlight go out while driving?

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Flex. When a headlight goes out and comes back on after cycling the switch, it's often a sign of a failing bulb or a loose connection. Over time, the filament in the bulb can wear out, causing intermittent failures. There could also be a loose connection in the wiring harness. If the problem has persisted for over a year, it's worth checking the electrical system and replacing the bulb to rule out simple fixes first. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
