I am planning on starting a PI/Security Company in Tennessee and am inquiring about the laws pertaining to POV lights. I plan to run amber/clear on my POV and company vehicles and just eondering if I would be within the limits of the law. Thank you for your time and comments.

 Just my two cents from someone who has been in the security business for a long time, those lights are pretty much legal for security vehicles. If you look up security cars throughout the US you'll see amber and clear on about 98% of vehicles. I live in South Carolina, right next to your state and the companies here use amber and clear on all their cars. But like uncledennis said just to be 100% sure call your local police department. Good luck with your new business. 

 Do check with your local LEO's on it but here is also a Wikipedia link on it.  I know wikipedia isn't completely trustworthy but most of the time they get it right. http://en.wikipedia.org/wiki/Emergency_vehicle_lighting#United_States
