I see them on the map!

According to a marine chart I have they are red lights that flash once 
every 5 seconds. You will need to verify that by a survey on the ground 
before adding the light data into OSM, since that chart is a copyrighted 
source. Beacon/buoy lights are usually only activated after dark, so a 
night trip would be required.

Do you recall whether the piles were painted a distinctive 
colour/colours? This information is also useful for daylight 
recognition. (using a "seamark:beacon_special_purpose:colour" tag)

For OpenSeaMap, the reefs should be tagged:

seamark:type=shoreline_construction
seamark:shoreline_construction:category=breakwater
