One of these is the Side Marker Light, which indicates a vehicle's presence and its dimensions. But even if you don't drive a truck or a trailer, installing this type of light is a great idea since it makes driving in poor visibility conditions so much safer.
Markers identify the pipeline operator and show a 24-hour emergency telephone number where the operator can be reached. The marker will state the material that is being transported within the pipeline. Markers indicate the general, not exact, location of a pipeline. Markers do not indicate how deep the pipeline is buried. Nor do they necessarily indicate how many lines are in the area. And, pipelines do not necessarily follow a straight course between two markers. Never rely solely on the presence or absence of pipeline markers.
