Crashondeck:
SVFR : A flight made at any time in a control zone which is class A airspace, or in any other control zone in IMC or at night, in respect of which the appropriate ATCU has given permission for the flight to be made in accordance with special instructions given by that unit instead of in accordance with the IFR and in the course of which flight the aircraft complies with any instructions given by that unit and remains clear of cloud and in sight of the surface.
So yes...you can fly SVFR in a control zone at night
