Bob Prehn – :
Best headlight I’ve had on a bike.
Bought two units so I could have one on helmet for night time trail rides. During summer months they are getting more popular in Colorado.
Also use for commuting.
Worked great on Glenwood Canyon Trail on a dark and wet night. Had great visibility in spite of wet trail as it did a great job of lighting up the path in front of me.
