I guess it would be cool if you put it in the right places, but some people do some pretty shady stuff to their cars with products like that.

I think maybe if the glow wire was used in a decent manner it has a possibility of looking good.

 

I've got a piece of EL wire that's 12V instead of 9V like that. The problem is mounting it so it doesn't look crappy or obvious... Got a plan in the works

 

like these other people said: the trick with EL wire is to make it subtle.

 

i suggest doing something where the wire will shine onto another surface but not be seen directly... cause, its way more cool then
