Why does the high beam indicator and running lights stay on all the time even when key is off?

The high beam indicator and running lights staying on when the key is off may indicate a malfunction in the vehicle's electrical system, such as a stuck relay or a short circuit. This can also occur if the vehicle has a faulty switch that fails to turn off the lights. In some cases, certain vehicles are designed to keep running lights on for safety reasons, but if they remain on continuously, it’s advisable to have the electrical system inspected by a professional.
