A cautious reverse brings to mind the ever-annoying yet necessary “eeh! eeh! eep!” of a dump truck or a big piece of construction equipment. But the truth is there are times when daily drivers should warn others of what they are doing. One of the best ways to do this is with back up and safety lights. Sometimes a simple rear bumper light or trailer hitch light can make all the difference in adding an extra bit of foresight to other drivers. Other times, during significant situations such as with snow plow trucks, strobe lights are a considerate attention-grabber to others by signalling something is going on.
