Sorry I didn't see this thread sooner.
I received these
http://j-w-racing.co.uk/product.php/9505/198/genuine_ford_led_rear_tail_lights_fiesta_st180_2016_ and I will tell you right now that the socket coming out of the UK tails is the same as the socket that our US tails plug into. I mean literally the same socket, so if you tried to plug and play it would be impossible. Basically you need to buy 2 US tail light harnesses here
http://www.tascaparts.com/ford/fies...at/tail-lamps-scat/?part_name=socket-and-wire to cannibalize the plug to adhere to the UK tail light. I had this professionally done and it looked great for 2 days until I found water had gotten into both tail lights and was pooling in the bottom of them. They are weather sealed differently and I have not taken the time yet to find out how. You will also need to have a Female Torx Bit set on hand as there is a bolt coming out of the middle of the back that needs to be removed in order for it to fit into our tail light frames.
I really want to put them back on but haven't had time to see if the weather sealing issue can be resolved and/or if I can totally get the moisture out of them without fogging in the future.
The effect is this: LED Stripes are solid on when parking lights/headlights are on and do not intensify with braking. The stripes are not the actual LED's but are highly reflective of what looks to be a tiny surface-mount LED strip behind those lines. The actual brake light is still a separate filament bulb and activates only when the brake is applied (not when the the lights are turned on). I know this sounds kind of weird but they really do compliment each other well. The LED stripes are awesome and while only really a decorative effect, are very bright and noticeable, especially during the evening hours (and obviously at night). I kind of like this in the fact that I've never seen OEM LED tails that are independent of a still-filament actual brake light.
If you purchase these particular ones there will be hurdles. Hope this helps.
