Turn signals aren't about fashion

I was walking across a parking lot today when I saw one of those cars (an SUV, actually) whose rear turn signal were blue - the bulb was blue, behind a clear lens. Now, I've already gone-off about how most people are bad drivers, but since 95% of driving is routine, it only matters 5% of the time, so it won't surprise you when I say that this is the kind of setup that I don't like. Here in New York State, a flashing blue light is a volunteer firefighter or the rear-end of some other emergency vehicle; blue turn signals fall into the category of WTF is that!? And WTF is one of the last things that a driver should have to worry about.

Clear lenses on tail lights are just as bad, during the day. They make the back end of the car look like the front end. Is that car coming toward me, or going away from me? Again, WTF?
