And while the Coast Guard often keeps aids to navigation at or near the lighthouses, the structures themselves mostly go unused.

虽然海岸警卫队经常在灯塔或其附近放置导航辅助设备，但灯塔本身大多没有被使用过。

Any light to attract the attention of another vessel shall be such that it cannot be mistaken for any aid to navigation.

任何吸引其他船舶注意的灯光不得被误认为是任何助航设施。

This lighthouse is an active aid to navigation, which means that the beacon still comes on every night, comes on at dusk, goes off at dawn, and it is continually maintained by the Coast Guard.

这座灯塔是一座活跃的导航辅助设备，所以灯塔每晚都会亮起，它会在黄昏时亮起，黎明时熄灭，并由海岸警卫队持续进行维护工作。
