I have not been high beamed yet after I installed this. I don't expect this to blind incoming drivers since they are so low to the ground. Honestly the lights barely hit the bumpers of cars in front of me so unless i'm on a wicked hill i don't think this will be a major issue. Quite honestly even if it did I wouldn't care that much if it helps me prevent all those idiots that likes to pull out of a side street directly in front of my car. I think the F10 is too quiet or something because I never had this issue with my previous cars because they all had louder exhaust systems.
