Thanks, I attached a pic link to my original post. See, I always learn something from the forum folks. Wax paper rolled up....I will try that on my next build.  There are so many options to accomplish effects on modeling I finally started to write them down in a notebook.  Thank you for the tip!

Whatever works for you is the correct answer.

I used 3 layers of wax paper to diffuse the LEDs but I think a glow stick tube would work well also.

A+ for imagination and creativity. Now let's see some pics

Here's photo of the nacelle lights. Please don't photon torpedo my post for calling the NCC-1701-D when its an E model! I can't type!  

The blue lights have 2 blue 3mm LEDs in each end. I could have used 3 and it may have been better.  The red tips are red 3mm LEDs.  Link: i873.photobucket.com/.../IMG_3233.jpg

Check out www.CultTVMan.com.  They usually have some aftermarket things like this available.

It does sound pretty darn cool, I'd love to see some photos too.

You wouldn't have any pictures available would you?  I have a NX class I'll be building in the future and it would be nice to see the engines lit.
