How do you reset dash lights?

To reset dash lights, first turn off the ignition and then disconnect the car battery for about 10-15 minutes, which can clear any error codes. Alternatively, you can turn the ignition to the "On" position without starting the engine and press the gas pedal three times to reset the warning lights in some models. If the lights persist, consult your vehicle's manual or a professional mechanic for further troubleshooting.
