Tamiya, Italeri, and Monogram all did the F-117 in 1/48, and Tamiya is very nice, the best of the bunch for fit and accuracy. Testors did it in 1/32, but it is not very accurate.
There is a website for model lighting in general with fiber optics and led’s, but I don’t have it bookmarked. Maybe someone else can tell you.
Another vote for the Tamiya kit. I have it on the workbench now and it’s a dream to build. Black Box makes a resin cockpit set for the aircraft, which is also good.
