Yes the o-ring...It was a pain in the ****. But ya the bulbs were 50 bux a piece..Big difference for sure thou..

 

you wouldn't ever need to take off the inner fender to get to the headlight bulb... if that was the case it's easier to take off the headlight housing itself..

held in by one ten mm bolt behind the headlight accessible by the grommet that pulls out in the wheel well... and two ten mm bolts up front and then it pops out.

but I never had a problem just reaching back down there with the hood popped and twisting them out.
