Interior under dash glow
 

Hello everyone! I'm new to the forum and want to get some peoples opinion on what I should do. I have a 2000 Honda Civic SI and want to do an interior under dash glow. I've looked into it and it appears I have two routes to go. I can either do a neon tube under the dash or a flexi-LED. I noticed that a 10 inch neon tube (the smallest I've seen them) won't fit under my driver and passenger side dash, I am also not sure where I can mount one in the back seat. Flexi-LED's seem like the way to go but I'm not sure how well they work or if they would look good.
Any opinions or experiences are appreciated!
Thank you,
Nick (blah91
