So my left headlight went out on m 06 lx 470 and I thought it was a simple bulb replacement. Never worked with HID bulbs before and this is the first time I have to replace them. Maybe I'm missing something pretty obvious or easy but I can't figure out how to go about doing this. Do I have take the whole thing apart to replace the bulb? How do I find the correct size? Not much to go off by in terms of branding to figure out the size or any how to's. Any help would be highly appreciated.
