as far as the glow light, its a personal preference thing, if you like it go for it dont be worried about other people thinking your rice. in my opinion id rather do suspension/ power work to the car before i spend money on the appearance, but thats just me im more of if its not helping me cut a tenth off my time then chuck it lol. but like i said its up to you its your car and if it makes you happy then go for it O0
p.s as far as messing with a friends car be careful man sometimes things can go to far, so just keep the jokes to harmless levels.
good luck with the pony :thumb:
