Why wouldn't your High beams turn off even with car off?

If your high beams won't turn off even when the car is off, it could be due to a faulty headlight switch or a malfunctioning relay that controls the high beams. Additionally, a wiring issue or a short circuit could keep the lights activated. It's also possible that the vehicle has a feature that keeps the lights on for a short duration after the engine is turned off, but this typically shouldn't affect high beams. If the problem persists, it's advisable to have the electrical system checked by a professional.
