Is there a bike light law?

They do see you. and you can be aware of them especially if you not listening to your iPod. Also they will have lights on. you can see the beam. The fact that I can ride without lights on the roads at night in London and get overtaken by vehicles who give plenty of room tells me different. I trust my own experiences. sorry if you can't handle that. HTFU

Sorry but as a driver as well that's complete bollocks. I can handle that no problem - it's your existence. You can fucking HTFU - in the emergency room.

You get plenty of room because people come up behind you and at the last second realise there's a cyclist in front of them and yank the wheel heavily to the right.
