i want to have a nice blue glow comin out of my grille on my 91 cougar. i wanted to know wat i should use. i went to streetglow.com and all i found were lights for the interior and underbody kits. i also went to my local autozone and they said they would have to specially order the lite. so basically can i use the interior neon lights for the grille or something else must be installed due to weather conditions?
