sorry, I know this is a pretty stupid question, but how do you change the headlight bulbs (lowbeam)?, I havent done it yet, and don't have my manual, but basically here's the deal, I took a look, and saw that theres that round black piece, which I assume you have to turn, and then the bulb pops out? am I right or wrong? I sat there for a long time, and couldn't figure out how to turn that black piece that seems to hold the bulb in the headlamp housing, any help would be greatly appreciated~!
