I am looking to get back into night riding. It has been a lot of years (over 20) since I last rode in the dark. None of my friends night ride, so I am turning here for advice. I just ordered a CygoLite Pace 750 USB LED Headlight and would like to get a second light. I will mount one on my helmet and one on the bars. Ideally I would like to have them interchangeable so I may go with another Cygolite. At night, I am going to do some trail riding and MUPs. It will be for my MTB 90% of the time.
Based on your experience, what size light would you recommend as a second light. Which would go on the handlebars and which would go on the helmet?
