Do not be afraid of the dark. The most critical thing you can do is buy the best lights possible. At a minimum you should be looking at a light 700 lumens +. Ideally you will have one 700+ on the bars lighting up the roadway on steady, and another 700+ on the helmet in flashing mode (the "hey I exist too! Now ya see me!" light).

Thw more light the better. I have 2540 lumens and I am already looking to double, if not triple the num of lumz blasting from the front of my spacecraft.
