Low Glows (neons) can be used as long as the vehicle is not operating on a public road. Everyone I know does it anyways. Around here cops arent TOOOOO picky about it, but they can get a lil pissy about them.
Changing the LP lights is fine. Never had a problem with that, my trucks LP lights are orange....Been Tailed a lot though
I have strobes in my truck. Not red and blue, but i have strobes and I have been hassled about them before but you are allowed to have any other colour (Been to court a few times and ruined some cops days' off for these)
Putting lil red bulbs in the headlights is generallly ok, you wouldn't be driving at night with out your Head lights on and these bulbs that you wanna put in there wouldn't even be seen when there on with the head lights on.
But this is MN, not Canada......But we're kinda half assed neighbors.....It may work out.
