We can indeed nail down a date for this:
CAIRO LIGHTS GO UP
FIRST CAPITAL TO END BLACK-OUT
By an order of the Military Governor, published last night, the black-out in Cairo ends to-day, and full lighting will be reintroduced...
The Times, 3 August 1944 (the story is dated 2 August 1944, so the effective date was presumably 2 August). It goes on to note that the Cairo blackout was by this stage not strongly enforced and was more of a "dim-out"; blackouts were still to be enforced along the coast and around the Canal.
