If they have an 'auto' mode and a 'manual' mode or 'off' position turn them 'off' and see if the symptom goes away. If it's remotely like the 2010 equinox it's anoying. Going in and out of shadey areas (trees around roadside) or clouds then sunshine , will cause the sunlight sensor to turn them on and off whenever the outside light changes.
