My recommendation is to go with Street Glow, Gold Series. It's kinda pricy, like $150 on ebay, but they have a lifetime guarantee against like almost anything, as long as the housing on the neons doesn't break...which is pretty ******' impossible. i had a friend who bought these, and had her car impounded. well, while it was there, they tried to take them off, and out of pure frustration, just broke them, but the housing didn't break. she called up street glow, they asked if the housing was broken, she said no, they told her to send them back to them and they sent her a new set in like 2 days. so yeah, i say streetglow, gold series. if you're gonna do it, don't cheap out. check out streetglow.com if you're really interested.
