The lighthouse was designed specifically as an aesthetic landmark rather than an active navigational aid for maritime traffic.
It is situated on the Oido seawall, which is part of a series of coastal dikes built to protect the Siheung industrial complex.
The structure stands exactly 21.6 meters high.
During low tide, the area reveals extensive tidal flats that are part of the broader Incheon-Gyeonggi coastal ecosystem.
The lighthouse is a popular filming location for Korean television dramas and variety shows.
Oido Red Lighthouse is a prominent 21-meter tall landmark located at the Oido Tourist Complex in Siheung-si. The structure was constructed in 2005 as part of the Oido Fishing Village restoration project to revitalize the local tourism economy. It features an observation deck accessible by an internal spiral staircase, providing views of the Yellow Sea and the surrounding mudflats. The area around the lighthouse is integrated into a seawall embankment that stretches for several kilometers. It serves as a central hub for the nearby Oido seafood markets and street food stalls. The lighthouse is characterized by its vivid red exterior and a traditional beacon light design. It is situated on land reclaimed during industrial development, now converted into a recreational coastal zone.

Bring binoculars if you plan to observe migratory birds or the tidal mudflats during low tide.
Walk along the Oido Seawall (Oido Bangjoje) connected to the lighthouse to explore the full length of the coastal park.
Visit the nearby Oido Prehistoric Site Park if you have extra time for a cultural detour.
Do not attempt to walk on the mudflats unless you are in a designated area, as the silt can be deep and dangerous.
The observation deck may be restricted during severe weather conditions such as high winds or storms.
