Supposedly that tiny sliver of light can blind oncoming traffic, and reduce visibility in fog. Other than seeing it when looking for it, it has never been a problem for me. And that oncoming traffic would have to be a semi about three feet from my front bumper. The last thing I'm worried about is blinding him at that point!
