I would imagine that wig-wag's, strobes, siren, etc. would be illegal in ANY STATE, not to mention the fine..... Unless of course you’re an EMT/Firefighter and have said equipment installed, but even then, there are restriction’s on the equipment you can use.(at least in Texas).
But 9c1Cruiser still hasn't answered my question about what his intent is by turning his car into a "cop car". I'm telling you man, YOU ARE GOING TO GET THE WRONG KIND OF ATTENTION. I think you really need to reconsider what your doing. Beside's drawing every cop's attention toward's you, you'll have people either slowing down in front of you making you EVEN later for work.
I'm not trying to flame you, just giving you some good advice
