Is the seal around the headlights absolutely necessary, or is it more of a "better safe and than sorry" insurance part? Mine has fallen off about 7 times so far and everytime I go in to have them reattach it the seal just comes back off after a few weeks. Sure it's free, no it's not an inconvience, but it sure is annoying. Dunno if I should just rip it all off the next time it starts to peel...what you folks think?
