About Range lights:
Imagine a lighthouse in the middle of land. Rear range lighthouses are not like most lighthouses and are often found inland some distance. They work in tandem with a front range lighthouse and line-up, one above the other, in the sights of captains at sea to guide ships through narrow channels. If the range lights are not aligned properly in the captain’s sights, he is steering his ship out of the channel and into dangerous waters.
This lighthouse is nearly 4 miles away from its front range counterpart and well into Delaware farmland. The range guides ships up the Delaware Bay and into Delaware River. |
