Dunwich Dynamo equipment and preparation

I've generally got on fine on the DD with just a CatEye OptiCube, but I can see quite well in the dark.

CatEye Opticube worked great for me the last two or three years. Unfortunately I dropped it and I think the lamp broke! Now I'm using a less bright LED which will just have to do.

Actually, I've never found it that dark on the DD, except for the odd tree lined bits.
