well to clarify, HID upgrades are NOT illegal if done correctly. They must past highway rules though to be legal. In the 06-09 fusions, the headlights are not setup to take the HID beam and properly project it on the road so the beam is scattered and blinding oncoming drivers . The 2010 models have projector lenses which are more suitable for upgrades. In fact, if you check a little bit online, there are already people who have successfully upgraded to HID's in 2010 models without blinding other drivers. You can swap out your headlamps for aftermarket ones with projector lenses, but the cost and end result normally aren't worth the hassle. But yea, I wish ford would stop playing catch up on small things like this and start leading the pack.
