Hmm... I think it's more of a show car thing and, yes, it would probably look pretty cool, but from a practicality standpoint, mosc is right. Not to mention a rock or other piece of debris could easily fly into your scoop and crack/shatter the neon tube(s) and make a mess, unless you have a mesh screen or some other kind of protection or the tubes are mounted safely off to the sides. LEDs are probably a better choice for that kind of application.
