makes the Indy scoop. There are others that also make them, but Fierowarehouse has the mold from DGP.
No one that I've ever heard of, offers the scoop with the strobe already installed.
That's not to say there isn't somebody, somewhere that does offer it, but I've never seen/heard of it being sold that way.
There have been people that have installed the strobe, but I'd venture a guess, the scoop didn't come that way.
If somebody knows where it can be purchased with the strobe installed, maybe they will chime in with the information as to where it can be bought that way.
