JDM Bling S14 Lighted Door Sills

Anyone know how much these go for and how it is to hook up? Did these come on all trims of S14 or only the K's model? I'm normally not a "JDM WHORE" but these things add a nice touch.

are you sure that light is factory?

looks sorta of like an aftermarket setup how the wiring and light is.
