Haha a highway code buff. Rule 115 says to use dip or dim dip in built up areas. Its the 30mph bit that is important and who drives at 30
Ford were the first to introduce dim dip which meant when yo put your side lights on the dip beams came on 25 percent bright..
However since they changed our street lighting to rotten white spot lights the roads round here are what I call badly lit at the best of times.

I also remember the dim dip headlights but since they stopped them many years ago I doubt there are many cars left that still have them - shame really as I thought they were a good idea meaning less likely to cause dazzle on brightly lit roads especially when wet. Anyway, Rule 115 is only advisory so again it is not an offence to drive on sidelights - it is Rule 113 which is "You Must" meaning it is a legal requirement, clearly states to use headlights at night except on roads with lit street lights. Confusingly, it states 30mph unless otherwise specified. As to what defines "when visibility is seriously reduced" I guess is open to interpretation.
What annoys me though are the idiots - usually taxi-drivers even though I am one myself - who insist on stopping on the wrong side of the road with headlights blazing which are directed straight into your eyes!
