0 either of the two smaller lights fixed on the front of a car
1 a piece of extra information that helps you understand something in a slightly new way:
What he said threw/cast an interesting sidelight on what had happened.
A general profile of the vertebrate brain, with sidelights on the ancestry of cerebral cortex.
To most people the lights shown in the drawing would represent sidelights.
I also think it is terribly dangerous to drive on sidelights in an unbuilt-up area.
As my noble friend has indicated, the lorry which is overtaking the car may or may not have its sidelights on, one simply cannot tell.
Well, if his car is seen before his sidelights, he is grossly deceiving himself.
I accept that many expert drivers tend to drive on their sidelights in built up areas where the street lighting is bad.
I am aware that circuits have been developed to reduce the intensity of rear direction indicators when vehicle sidelights are switched on.
At present the only condition imposed on drivers at night is to use their sidelights.
