Lighting Question

A friend of mine turned me onto this site.. I have been thinking about
lighting up my bike but don't know to much about it... The site below has
NEON and LED.. My question is which is better/more reliable?. Both of
these
come with a "lifetime if it burns it gets replaced" type warranty but I
don't want to be changing out neons every other ride or two... Anyone have
any experience with NEON they can share?

Nightmares? Also, what about lighted plug wires? They look cool as hell
but are they reliable? I would hate to get stuck in the middle of nowhere
because a neon tube broke when I hit a dip...
