na, i see many riced civics with aftermarket tailights. almost all of them are completly silver /white with maybe a small red ring as to where the bulb is located. Dont think there a law involving colors, cause wal-mart still sells em!
i saw what i was thinking about in terms of taillights on the new mazda speed3. look at the tail lights.. they are clear and just the brake light comes on in red. does someone make something like that or can someone custom make one?
