Grange Hill was long-running children's series, mainly set in school classrooms with some exterior filming. All cars will probably be background street scenes or possibly teachers car park. A great series which most UK contributors under the age of 50 will have watched for a few years at some stage in their lives, so could well be worth an imcdb entry.

The cars in the picture are (right to left) a late Merc [W114/5] with groved lights, 1969+ Viva HB 4 door,and 1969+ Escort Mk1 van - mildly interesting but typical of period.

In terms of the lighting, these big format lamps were used a lot in 70s or 80s on main roads, but high electric consumption so abandoned in 90s for more efficient/compact formats.
