Have Lamin-X on mine since May '14 & glad I did. Had several rocks hit the headlights, but headlight didn't break/crap nor scratch on it.
If you don't wanna pay that much from Lamin-X then buy uncut clear protection film and you cut it in headlight shape. You can get 3M and other high brand for $10~$30 to do headlights, foglights and DRL.
