You actually can't replace the light by itself without some mods to the housing the bulbs sits in. It is designed to be replaced as a unit. You can actually just replace the bulb if you use a dremel to cut some slits and allow the bulb nubs to come out.
This may help(someone said the assembly does not have to modified BTW so you could try it) : http://www.bimmerfest.com/forums/sho...d.php?t=417609
The one thing I have not seen is instructions to get the socket out(as you asked). I have never looked at mine. I ordered 20W bulbs to try but never installed them. I am glad as I just read they will melt the socket.
