Are you sure that it is bright enough outside that car should switch it do DRL's? It's not going to switch over every time the sun shines to sensor or you drive in the woods where it is darker. The system is smarter than that and if lighting conditions are borderline then it will stay on low beams.

If you live in northern latitudes, give it a month for sun to get higher before you jump to conclusions and possibly change hardware without a reason.
