yeah... i'm a little miffed about the positioning of the neon tube on the drivers side, but it's pretty much too late. the tube can't really be seen on the passenger side neways. if you look under your drivers side dash, you'll notice that it hooks inside a little bit, like so:

The neon tube is where the () are. i basically screwed the neon tube to that little hook-in part. Unfortunately, that hook-in part is pretty small, so when i screwed it in, the neon extends out a little. How did you do yours?
