All you need to do is refer to this
http://www.highwaycode.gov.uk/09.shtml#103 and the following few articles, it's all in there.
Except it isn't all in there, is it. You know as well as any of us that the rules regarding what is and isn't a street-lit road are bloody confusing and aren't aided by local authorities who are seemingly unable or unwilling to perform simple maintenance of speed limit repeaters. If we were to interpret the HC literally, then what speed limit would apply in the following scenario?
A dual carriageway with street lights. On entry to the dual carriageway the driver passes a pair of NSL signs marking the end of the previous lower limit. Along the entire length of the dual carriageway the driver passes NO OTHER speed limit signs until they reach the end of the dual carriageway, at which point they pass a pair of 30 signs marking the start of a new lower limit.
Before you idly dismiss this as a completely fabricated and unrealistic scenario, I should point out that whilst I realise the chances of every single repeater being missing is remote, even with the current average level of sign maintenance, it's NOT uncommon to find a stretch of road where sufficient repeaters are missing/obscured/faded into illegibility such that the distance between visible repeaters is greater than required. Thus, whilst a driver may eventually pass a repeater and have confidence in the actual limit, it is quite possible for them to spend an unacceptable length of time driving along such a road with NO clear guidance as to the limit.
