In Utah, you can't have ANY blue flashing lights on your rig, anywhere, unless you're law enforcement. For emergency lights, you can't have a red light that's visible from the front at a distance of 75 feet. I've thought of the same style of LED's for emergency flashers, but not for constant illumination.
My understanding is that 'non-emergency' vehicles aren't allowed to have any 'flashing' lights (except for emergency flashers, which aren't on all the time) while the vehicle is in regular motion. That's why you can get away with a 'modulating' headlight over a 'flashing' one. I'm not a LEO or lawyer though, so you should read up on your states laws for lights on your vehicle.
