Dim Dip? I vaguely recall that from the late 80s. So I did some research and found that it appeared in the UK, and only the UK, in 1987 and was declared illegal by the EU in 1988 and was then discontinued, disappearing by 91 or 92. So Colin's car must have been one of the last with "dim dip".
The dim dip module was essentially a simple voltage dimmer and relay, making the headlamps come on with a dull light when the sidelights are turned on. So it can be totally removed, headlamps need dip and main beam.
Given that daytime running lights are required on all car and van vehicles type approved after Feb 2011 it will be interesting to see how Morgan deals with this whenever they bring out a new model. Possibly the fog lights could be used. Or even better the wing mounted sidelights with a bright enough LED.
