Lange Jaap ("Long Jeep"), also known as Kijkduin Light or Den Helder Light, is an active lighthouse near Fort Kijkduin in Huisduinen, Netherlands. At a height of 63.5 metres (208.2 ft) it is one of the tallest "traditional lighthouses" in the world. For almost a century, from 1878 to 1974, it was the tallest lighthouse in the Netherlands, until the construction of the Maasvlakte Light.
