This, so much this. I'm having no issue with new cars and their LEDs. The aftermarket kits that are installed on 1994 Swifts and Passat B5s are not at all configured properly. They just throw it on the car and "yay i can see more" and sometimes I even think that they are using their high beams. But no, it's just their incorrectly set up lights.
