This is a High Quality Headlight activation motor for a 1966 or 1967 Buick Riviera (with the bracket attached). The motor is designed to activate the headlights and is in excellent working condition. It's a great replacement if your Riviera Headlights are not turning when you hit the switch. Whether you are restoring your Classic Car or just need to replace the one not operating in your Classic Riviera. [This came off a "67 Riv however I understand it will fit other models. However you might need to remove the bracket.]
