I have to ride in the dark for at least part of my commute from September through April. Personally, I would rather ride in the dark during the morning leg of my commute because there is less traffic then. So, I am not crazy about the time change in the fall, which means most of my ride home is in the dark during the heaviest period for traffic. However, I am probably more visible to drivers in the dark because I have an very good light system with two headlights and three taillights.
