This is the High Light that stands at the apex of the triangle formed with the two Low Lights (North and South).  It is still an active light working in conjunction with the South Low Light to define a range marking the safe passage through the lower reaches of the Humber.  Some sources suggest that, before the lighthouse at Spurn was decomissioned, it also worked in conjunction with that light, although how this was arranged and what range it marked, is unclear to me.  Although the tower is nominally "stucco covered", most of the stucco has now peeled off.  Public access to the riverbank is no problem but, in photgographic terms, a visit in the early morning or late afternoon would probably result in more favourable lighting conditions.
