Recently purchased a 2010 Beetle Convertible and I'm considering changing the headlight and tail light bulbs to LED. Is it as simple as changing the bulbs, or will there be a problem with the computer recognizing the new bulbs? Next question, the car did not come with fog lights and I'm also considering adding the VW OEM fog lights. I have compiled the parts list which include grills, fog light housings and the light switch. Is there a wire harness I need to order as well to get power to the fog lights? I'd just like to know what I'm up against to do this install. Thanks in advance for your comments.
