Do you have pictures of the actual black light you installed and location? I ordered some led strips and I'm waiting to get them in. It would be nice to see what you've done.
I ordered mine from ebay, via a seller named POMBOTECH". I got the set-up that included the black light LED strip (self adhesive back), with the needed power plug and adapter. The whole set-up came to $34.99 shipped.
Here is a link to the ebay item, if the link eventually dies for whatever reason, you can simply do a keyword "black light LED strip'", and look for the seller I mentioned.

Here is a pic of the item from the seller's listing, so you get an idea of what it is.
As for the instalation, I mounted the strip to the inside left/right side walls, just below the glass line, and simply the line of the glass (just below the glass line by about 0.5-0.75 inch below the glass line inside the machine. I liked this locarion as it doesn't shine directly at your face/eyes--since it is angled at the PF, and I also felt it gave a nice even coverege of all areas of the PF and such.
You should be able to get a basic idea from the pic below (it's one I had taken previously, but if you need, I can get another pic for you)
