I had the same problem. I even took my car to get a full on detail and they used the plastic x or whatever it is and sanded the crud outta my lense - they looked slightly better but still hazed. The guy even said "thats probly the last time you should do that, its about time for new headlights"...... So I just went to Wal-Mart and got their "headlight restoration kit" - it's not Wal-Mart brand - its in a silver pouch (usually located against the furthest wall in the auto-area) - and you wet-sand the lense with the first brown sandpaper provided - clean them off - then use Some chemical I think called CV-2 - and it LITERALLY forms a new plastic coating over the lense and fills it in. My headlights were done a year ago and they STILL look like new ones. Just take your time with the wet-sanding and it will last.
