lighting for fuel gage, oil gages, etc. on 172N

Hi,

I have lit my entire panel, via a combination of "nu-lites" and
instrument replacements of instruments that were internally lit.
I am quite happy with the result, but I still have dark fuel,
oil pressure and temp gages, and the ammeter on my Cessna 172N.

I have searched the web quite a bit, I cannot seem to find a
reasonable solution for these instruments. I know that people
have found a way to light them up, because I have seen photos
of same (see www.avweb.com, the "photo of the week" contest).

I'd like to find a PMA solution that lights the gages evenly
around the edges, just like the nulites. The only PMA solution
I have commonly seen is postlights, which I don't really like
the idea of.

Thank you.
