If you look at the headlights, they have a grey surround as opposed to chrome like the standard headlights. Also, the dipped beam is in an optical 'dome' rather than a reflector. On top of that, when you turn the steering wheel between (iirc) 6-28 mph, there are additional lights at the outer edges that light up to help you see as you turn the corner.
Very interesting, you know your stuff. Thank you! I might have a buyer for the Zed so I can focus on the Clio. It's had the MOT, spent £750 on 3 new tyres, handbrake cables, ball joint, battery, brakes calipers and discs, oil, bulbs.
Going to fill it with momentum and see how it's drives tomorrow!
