actually I have the exact same question. I got a set of Philips Xtreme Vision bulbs in H11 for low. I opened the hood up the other day and I cannot see how one can reach into the very corner of the engine bay, twist the bulb loose, disconnect the lamp from the wiring harness, replace the bulb, reconnect the harness plug, and replug in the whole thing with a normal size hand, all that single handedly.
The high beams are doable, but the driver side still requires taking off the airbox.
Since these cars have been out for 4 MYs someone must have changed their low beam bulbs, did anyone do it without taking off the bumper cover and unbolt the headlamps assembly's?
