Often times, the Dodge Ram marker light goes unnoticed, but it’s actually an important part of the vehicle. It’s ironic then, to say that the purpose of a marker light is to provide better visibility to other drivers at times of decreased road visibility. Marker lights come in various sizes, shapes, and even color lenses, all of which are governed with industry regulations to ensure that the roads are safe for driving on. The Department of Motor Vehicles, upon registration of a new vehicle, checks to make sure that all of the necessary parts are present and legal. In fact, I failed the initial inspection of my truck when the inspector noticed my Dodge Ram side marker was no-where to be found. This type of part is easy to replace, and a replacement part can be found with any online automotive part vendor like Go-Part.com.
