Some peeps on here will tell you not to get the ones off ebay and only to get the original ford ones. I got the ebay ones and they look really good. There is a little bit of water in them but that aint that bada problem.
To change them, get a credit card type card and slide it under the lit on the top edge. the spring clip on hte bottom will compress and the top should pop out. 5 mins a side but make sure you don't lose the bulb holder in hte wing or it could be a lot harder :L
