Not all custom buildings have the night lights feature. For the one's that do, you need to update your program to build level 640. I would tell you how, but first I need to know which program version you have. Navigate in windows explorer to C:\Program Files\Maxis\SimCity 4 ...\Apps and hover your mouse over the SimCity 4.exe file. If you are running windows 7 it should tell you the version which includes the build number; on other versions of windows you need to right click to access the version.
