Like you, I don't ride much at night, but stay ready. For a number of years, I used a 1 watt
Brinkman headlamp that produced about a 100 lumens of light. About a year ago, I moved to a recumbent. Switched to
Nebo Redline 220 lumen flashlights. I sometimes also use the headlamp as I like being able to point a light in the direction of an upcoming turn.
Where cycling lights are concerned, more is better.
