I wouldn't count on getting an aftermarket warranty to cover your headlights.........it would be considered normal wear and tear. I am assuming you own a 2000 LS? If that is the case, I would just find some on ebay and reseal them........easy job and if done right, yield amazing results. If you don't want to do this, chances are that FLM has updated the part with a revised edition, thus keeping the number of the part the same or updating the number and eliminating the other one. Either way, I am sure that whatever you order, they will send the revised ones.
