About Brownsville Channel Inbound Range B Rear Lighthouse

A 22m square skeletal tower serves as the rear marker for the Brownsville Channel Inbound Range B. The structure supports a red rectangular daymark featuring a white vertical stripe. Emitting a green occulting light with a 6-second period (Oc G 6s), it functions in conjunction with the front range light. Situated on the north side of the channel approximately midway, it aids vessels navigating towards Port Isabel, located 4.7 km distant. The site is accessible to the public, but the tower is not open for entry.

Why it matters: This range light offers navigation assistance for commercial vessels transiting the Brownsville Channel, a main shipping route for the port of Brownsville. Its specific green light, visible only when aligned with the front marker, indicates the correct course for mariners to avoid dangers.
