Outdoor post light does not function well

[ward]

前门屋外草坪上的照明灯，本应该白天自动关闭，现在已经一直亮着。估计是光敏开关不工作了。请问如何修？多谢

Thanks but where is the sensor located?

Found the following how-to instruction. Will give a try.

Btw, is this owner's responsibility to buy and replace the failed photocell sensor? or we need to call the city?
