Last time I looked it up in Ohio, their particular set of rules were:
1)no blue lights period
2)no flashing lights period
3)neon lights (the actual tube)cannot be seen, but the glow is undefinable (you can get away with it)
4)red lenses should face the rear
5)white lenses with colored elements(including red)are illegal unless OEM
6)maximum wattage for any light 55 watts

This was a few years ago and Ohio gets their jollies by changing the rules.
