On my ride, if I have lights or reflective strips, they should spell out the word "V I C T I M", in those neighborhoods I prefer to not be seen from a distance, I can avoid cars since I can see them, you just have to make allowances for the fact they can't see you is all. Plus, without lights, you have to ride slower.
