The Life-line is a safety indicator installed to the street lamp. Roads in winder are always covered by snow due to the weather. Driving on these roads is always dangerous no matter in the day time or night, because the driver could not decide the boundaries and trends in the totally white world. The Life-line is designed for this. Red arrow indicator makes it easy for drivers to judge road boundary and direction in any extreme weather, guaranteeing their safety in a better way.
