[A bones]

In days gone by some residential townships did not have adequate street lighting. The ordinance for street parking after sundown would require cars to have that light on the left rear fender. A weak wattage(to diminish batt drain) bulb would would have its glow diffused by the jeweled lens. I always thought they looked eerie when going down a road with all the cars dimly glowing.
