To add to the discussion regarding daytime lights, I used to drive with front foglights on, but recently a Police car drove up beside me at traffic lights and the officer asked why I had my lights on as it “looked odd”. He insisted I turn them off, which of course, I did. Now, I use my headlights, dipped to the maximum using the beam-height adjuster switch. At night, I simply re-adjust the setting. This seems to work without blinding oncoming drivers. I think DRLs signal to pedestrians that a car is 'On' and moving, rather than 'Off' and stationary. I have no evidence to support this hunch, however.
