When I drive at night my dash lights and radio lights dim and brighten. on 2006 Chevrolet Silverado 1500

I have nothing covering the sensor by the windshield and it doesn't do it all the time and it only does it at night. I check the alternator and battery and are all good. Could it be the headlight switch or the turn signal switch
