mine suffered from a really bad light pattern, the cutoff was completely washed out, virtually nonexistent, that i ended up either having to turn them down so far that i barely got to see anything or blinding all oncoming traffic. put OEMs back in, problem solved. obviously rear lights won't be suffering from this but i wouldn't be at all surprised if they come with their own host of issues.

once bitten...
