What do the side marker lights on cars do and how do u turn them on??
Not quite sure what you mean by side marker lights, but sidelights are a setting on the headlight control stick and running lights are on all the time when the engine is running. Cars with running lights often don't have sidelihgts. The purpose is purely visability. Running lights were developed for countries where visability is often less than perfect, and are actually quite bright. Side lights merely mark the edge of the car.
Side marker lights come on when you turn your head lights on. (IF you have them)
These are reflectors, they are for cars to see you when you are crossing in front of their headlights......Some tail lights wrap around to the side and are on when the headlights are on.......Nuf Said
Side marker lights were introduced in 1968, a year that included a lot of changes in American cars. It was the first year that many features that you find as standard equipment on cars today were introduced like shock absorbing bumpers the lane change feature you find on your turn signal and seat belts. Before 1968 bumpers front and rear were really just a styling feature and didn't have any shock absorbing properties. The side marker lights or reflectors were part of the package of new safety features to make cars visible at night from the side in addition to yellow running lights that come on automatically with your headlights. These were introduced to make cars more visible when one headlight might be burned out. It keeps a car with a burnt out headlight from looking like a motorcycle at night.
There are 2 diffrent types of side maker lights , lights and reflectors. they come on when your lights are on.
