Kai Tak Approach Lights at junction of Hau Wong & Nga Tsin Wai Roads [????-????]

Notes from Moddsey:

Counting from the runway in a north-westerly direction, this crossbar was Bar 3 (later renamed Bar 4 after the runway extension was completed in 1974) of the Runway 13 Approach Light System. In later years the pylons would be removed and the lights were installed on the roof of the building.
