I have a video on Youtube showing how to install LED strip lights under the lense of the exact same Jc Whitney Trunk.
I can't link it right now because I cannot access Youtube through the work server.
"Marauder GZ 250 LED tail lights - YouTube"
Type those words into google and it will be the first video link that you see.
I believe there is a brief description of what I used and how to do it, IIRC.

Here is the original post I made about it. Lots of good lighting info in that thread. Read it all. The link for the video is at the bottom of the page.
