I'm a new FFE owner however, I've been messing around with aftermarket HID lighting systems with all of my previous cars for years.
I did some research on the FFE HID system, its apparently an OSRAM D8S system @ 25W. The light output is ok but I believe can be much better with 35W systems and other bulb selections. D3S is the other common spec, the only real difference is that D3S operates at 35W and you can find a plethora of bulb sections for that. The only mechanical difference between D8S and D3S is a notch location on the bulb. I found someone who did this conversion. on an ICE focus

Has anyone successfully performed this? Also does anyone think going to 35W system will affect the range on the FFE significantly?
