What state are you in? A lot of times the laws differ depending on where you live. If you're in Cali, then you can search for laws
here in this database.
Oh, and if you don't want to get pulled over for being "suspicious" or whatever, then don't change your lighting at all. When I got my last ticket ( 4 fix it citations on one ticket

), the cop didn't believe that my tails were stock. Of course, the 99/00 civics come with the red/clears stock, but the cop gave me hella crap about mine, trying to say that they weren't stock. I ended up not getting a ticket for the housing of them, but rather the white bulbs inside.
Anyways, hope that helps.
