Months ago I installed a Big Ass (brand) LED in my Summer home. Began to notice that when dark out, and taking my car out, the screens would not dim. Unless I switched them to manual. Waited half an hour of driving to no avail. Finally determined that the super bright LED was making it think it was daylight. Asked service; they were oblivious. Then drove to Winter home and charged on way at dark at Cincinnati (Blue Ash) ... it is lit with very bright LED's. But probably 16 feet up. not 7' like my garage. As I left there, same thing happened. Spent weeks at Winter home where there's no LED and the problem didn't manifest itself. Anyone else see this? Is it a design flaw or do I need a new sensor in the rear view mirror?
