Lights on when raining, or foggy @AlanSeallsWeather

Lights on when raining. That's a road sign you see in many states that tells you your headlights and tail lights must be on when it is raining. The purpose of having headlights and tail lights on is so that you can be seen by other drivers, when visibility is compromised. Some people assume Daytime Running Lights (DRL) will take care of that, but most DRL do not turn on tail lights. While driving in fog, your headlights and tail lights should also be on for overall safety.

$A Sun Dog is a Mock Sun is a Parhelion Sun dog is the nickname for a bright spot of color seen on either side of the sun in cirrus clouds. It follows the sun the way a dog follows a person. It is also called a mock sun because it imitates the sun and sometimes seems just as bright. The technical name is parhelion if theres one, or parhelia if there are two. Its a distant cousin of a rainbow. To get a sun dog, you need to have cirrus clouds, which are very high, and very cold, and made of ice crystals. The ice crystals separate the light into seven colors. Thats called refraction. Sun dogs are pretty and interesting and common. They simply tell you the clouds are high, thin and cold enough to be made of ice crystals.
