Do you have the original generator, with the little cutout box on top, or do you have a modern alternator fitted to the car? If you have the original generator, then that is normal. If it charges too much, you can adjust the third brush to cut down the output. The Service Bulletins explain how to do that. If you have a modern alternator, there should be no difference if the lights are on or not.
