Wow, all of these are great ideas! I'll have to look for those paints & I may try the florist wire idea!
Here's how my tail lights turned out. I made a box to mimic the inside of the light assembly. I painted the box three different colors of silver, giving the colors a hard, masked edge to hopefully mimic a faceted interior.

Then I streched some clear sprue over a flame till I got a thin rod & trimmed it to the size I needed, then "bulbed" the tip by bringing it close to the flame. I glued it in place, colored the tail light with red food coloring & Future & volia!!

It looks so cool!!! I put bulbs in both the red & white sections of the tail light. I still have yet to trim the assembly in silver to get rid of those chips, but I'm real giddy with it. The clear glue dried a bit chunky, but overall, I'm still pleased. I still have to put in some wires leading out of the back of the box & down the roof line, like I saw in one of our cargo vans at work, but that shouldn't be too hard.
Thanks for the ideas, everyone!!
