Some just need a clean down and repaint, some need a little rejig to ensure the lanterns are as visible as possible. When you have an asset reported extinguished, be sure to check that its not something as simple as a design creep over the years of engineering which has lead to the obscuring of the light head; the top light on the Port Hand Bi-form pictured has been reported as extinguished, on checking, the lantern is fully functioning but the brackets installed more recently position the light head directly in line with the daymark, obscuring the light from upriver.
