Can anyone tell me how hard it is to replace my stock D3S bulbs and replacing it with an aftermarket 6000k D3S bulb? I looked under the hood and it doesn't seem like there is much room to remove the bulbs. Can someone give me some directions on how to do this? Thank you!!!

Mark the headlight housing bolts (torx) where the washers line up with the sheetmetal using a silver sharpy marker. This is so when you reinstall the headlights, they're lined up right where you have them. There's a few bolts only that hold it in on each side. Look for the one down below in the back. Then they just slide forwards and out of the car. Put a towel down on the ground so when you do set it down it immediately is on a soft surface. There's only a couple of wire connections that are easily removed. Then the back of the housings pop open and you've got access to everything. It's a pretty straightforward job. It goes without saying don't touch the bulb. And the first time you turn it on, let it burn in for at least 15 minutes before turning it off. If you're replacing only one side, expect it to look different (color temperature) for about 10 hours of driving with them on.

I did a DIY for the S4, a lot of the frontal area is the same, even though the light housing itself is different, this might help:

So I reviewed the link and it states that the S4 stock ballast is 35w. I was told on this forum that the S5 stock ballast is 55w. Can someone please confirm that the 2010 S5 stock ballast is 55watts? I was looking into swapping out the stock bulbs with 6k bulbs. Thanks in advance.
