OK, so I understand it that a 15 year old car has headlight bezels that are a little yellow. That's fine. But when I buy a turn signal lens, shouldn't it last at least a year before it turns yellow?

Just to warn you all off, the company I bought it from was newandusedvolvoparts.com. It was a good price; I guess now I know why. It's been like six months and already it's as yellow as the original headlight bezels.

Do any of you know a good source for aftermarket lenses that won't turn yellow the minute they're exposed to the sun? Should I stick with the dealer for these items?
