Sir – Driving on the A40 from Wolvercote roundabout to Witney at about 4.30pm the other Sunday, there was a continuous stream of traffic heading in the opposite direction towards Oxford.

I counted 10 cars that had no off-side headlamp.

Don’t they realise they look like motorbikes and could be hit if someone decides there is room to overtake? Two other cars only had off-side lights.

Come on motorists. Use your common sense. Although your lights help you to see, they are primarily there to allow other people to see you.
