Is it legal or illegal?

not sure if it's legal but it'd be a damn good tool when the jackass behind you has highbeams on or honks at you for no reason.

if you want to show to other motorists that you're POd then do what im doing. Make a light-up middle finger for your back window

Believe me, I'd love one in my car too. Too many bored cops for one little town and I'd get called in too often,

I do have an internally lit HUMBUG sign for the holidays though.
