Yes, but you've got it the wrong way round. The speed limit applying to a road is determined by whether it has Restricted Road status or whether it has a Speed Limit Order applying to it. The presence or absence of streetlights or repeaters can affect the enforceability of the limit, but does not itself change the limit without the necessary traffic regulation order.
Peter - can you please explain Restricted Road status? I am even more confused after these posts.

What I mean is that each road has a specific legal status. A Restricted Road is a road with a 30 mph speed limit which has a regular system of street lighting and so does not need repeaters. Any new urban road that was built would automatically become a Restricted Road unless the council varied the speed limit by means of a specific Speed Limit Order.
A council cannot change the speed limit on a road simply by putting up street lights - it also has to go through the legal process of changing the road's status.
Likewise, the speed limit on a road cannot change from NSL to 30 simply because street lights appear - the council have to erect 30 mph terminal signs to mark the change in limit, which also has to be backed up by traffic regulation orders.
The following page on the ABD website will help explain the legal situation:
