the Blue line series kicks ass. it's just as bright as the gold line, and way easier to install. the tubes aren't wired in series, they all go to a distributer so if one tube breaks, the rest will still work. not the case w/ the gold line series. I dislike the LED kits /cause they are about 1/2 the brightness of the neon kits, and the lite glow kits are just cheap knockoffs of street glow ones.
