I have the base model, and want to replace the stock halogens with Osram Silverstar bulbs, but the headlight assembly is integrated INTO out crazy looking front fenders, that access from the engine bay is almost impossible.

what is the correct way to gain access to the low beam headlight bulbs???

first you have to take out your 2 front wheels.
jack up your car
take out the undergaurds once you taken out your wheels.once you got it open you can see your low beam bulbs

good luck

You don't need to remove the wheels. Turn the wheels all the way one way and go through the wheel well.
