Nice try, but that's a miss. It's usually the teenagers on their mountain bikes or BMXs that ride along at night with no lights. Though I've also seen on another cycleway some older guy get really annoyed at someone for having front lights on a bike, while this grumpy old guy was riding along in the dark with no lights at all.
Everyone else I see on the M7 at night has lights on their bikes, and they are all on road bikes. And I am riding on there a lot of times now at night, so I do notice.
