Cops
probably aren't giving you a hard time because they know for sure you aren't a bike cop. They might be happy to see that you're well-lit at all, too (visually speaking, not "lit" on drugs..

).
Drivers, though, are a little paranoid about flashing blue lights in their mirrors (either they think they're being pulled over or they're trying to get out of the way), and they pulled over in response to yours for that reason. If I were driving and saw some flashing blues behind me, I'd move aside, too. That could cause a real problem if a driver moves right while you're hoping to pass on their right.
Best to avoid confusion, I'd say, and stick with red to the rear, white to the front, and reflective stuff and/or amber lights to the side.
