I just went to the dealer's service team on Saturday, December 27th and they are unfamiliar with the difference between the Mondeo and Fusion lighting. I told him the Mondeo is essentially the same car as the Fusion but sold exclusively in Europe to which he replied that it's unlikely they will get the part because of it.
Now, I'm sure we can order the Mondeo lights online but I worry about its ability to be plug-and-play. He noted that with the Lincolns that they also sell and service, computer systems need to be noted that it's a HID not a Halogen. Not entirely sure how that makes a difference but the most important point he mentioned was cost. Lincoln HIDs are selling for $1300 for the entire housing per headlight putting you at $2600 just for the housings and god forbid you get it done @ a dealer, you're probably looking at $400+ for labor when in reality, taking off the bumper is pretty easy.
I recommend checking with your dealer to see if your answer is different (which I hope it is) but with my unfortunate experience and potential price quote, I'm going to opt for these retrofits. Not to mention, the current Lincoln housings are JUST HIDs, they don't even have LEDs and they definitely don't have the turn signal switchbacks or sequential. My fair guess is that they will cost at the very least, the same as the one for Lincolns but in reality, probably double the cost of the Lincoln HID housings.
The ones on this site come with a two year warranty on parts that we can't replace (basically everything except the bulbs). Even if I have to buy these two or three times over a 6 year period, I may still net even with newer headlights 5-6 years down the road.
Btw when I say this site, I mean the one that Sd driver posted @ http://www.thelightingfirm.net/product/13-15-ford-fusion-led-mondeo-style-led-headlights/
Also, for 2014 core returns they give back $175 for the pair of headlights. If it's going for better on eBay, that may be more worth it but it's a guarantee of at least $175 off of the order.
