custom? my bad I thought they were the ones from ford when I posted my last reply...but for those of us stateside I originally tried to "build and price" buy my car online and it didn't really work out for me that way, but when I "built" mine online illuminated door sills were one of those options I checked yes to. So while they are over double the price (free shipping if you ship to dealer) ford does offer some. Id love to get them, I dig the look. But I really like the ones you installed XuperXero, I especially like the way, in the video, they seem to pulsate a couple times before staying on. good job....
for the states, if you wanna fork out 195 bones, heres the link
