just last week i was at a junction trying to turn right with a cyclist standing at the edge of the road on the right with his lights just blazing right at me, he was waiting for me to go presumably because the road was clear but i couldnt see past his light. i was just putting down the window when he got impatient and moved and went behind me.
this is just one case of many.
i also have some fairly bright bike lights which i dim and dip on the road but its not ideal.
tonight i went for a night run in the park with my 150 lumen torch, not 1500, 150 you just cant see past it at night, had a few dog walkers comment on it and its just a fenix torch.
people just need to be more respectful of others around them with their lights, idealy there needs to be a road mode on lights. wont be long before accident start to crop up from blinding lights.
