In turning the switch the diameter of the thimble seems to be a little too small and not sufficiently clear of the push button ; also not sufficiently clear of the key, if this latter is left in place. There is a general opinion here and amongst Sales that the instrument light should be capable of being left switched on for certain purposes, e.g. looking at the map with the car stopped. EFC. | ||
