The tower is brick masonry, and has 110 steps inside with no intermediate floors. Originally the light was equipped with a Fresnel lens system, and it displayed a white light towards a sector clockwise from south to northeast. There were two lighthouse keepers and a master until 1962 when the lighthouse was automated. A pilot station was built next to the tower, currently the pilot station serves as a hotel.

The lighthouse also houses a smaller sector light that is used to guide vessels to and from the fishing harbour. Today the lighthouse also houses a webcam.
