My headlights on my LX were yellow and nasty so I thought I would try something. I took some of my NXT metal polish (http://www.meguiars.com/whatsnew/nxtproduct_page.cfm?SKU=G-130) and buffed my headlights with them. They look great now. I don't know how long it will last but it was cheaper than buying a headlight restore kit.
