take the mount screws out take the bulb out reverse to put back together don't mess with the leveler
Looking at the bulb, I'd suggest you open your hood and look at the back of the headlamp. There should be some kind of plastic collar that you would spin, then remove the bulb assembly... would be my guess. You can see what the bulb looks like http://www.amazon.com/Wagner-Halogen-Light-BP1255-H7/dp/B00FI14IUE/ref=sr_1_3?ie=UTF8&qid=1418164688&sr=8-3&keywords=WAGNER+Part+%23+1255H7
