That looks great, good idea to use an extra OEM light so they match.
I can easily get some nice LED's to put in your guys' dome lights. I'll probably order some of them tonight to test out. I'm also on the search for alternative lighting for your cargo areas since I know VX parts are hard to find, and finding an OEM dome light might not be the easiest thing.
EDIT: Just looked on Isuzuparts.com and an OEM dome light assembly is $65 plus shipping. Ouch..
