asked the Secretary of State for Transport if he will take steps to amend Statutory Instrument No. 1487, 1969 to allow councils discretion to erect additional speed restriction reminder signs on dangerous roads, irrespective of whether there are public lighting posts at frequencies in excess of one every 200 yards.

No. There is at present a clear link between lamps not more than 200 yards apart and a 30 m.p.h. limit, unless a higher limit is indicated. To allow 30 m.p.h. reminders on selected roads could only cause confusion.
