I cycle to and from work every day, and I've tried loads of different lights. These are by far the best because:
- Easy: Put on and take off in seconds - no wrestling with holders. - Compact: I can shove them in my pocket when I go somewhere. - Efficient: Use LED, so they are brighter but use less power than conventional ones. - Attractive: Really nice looking, and when they're off you have no ugly plastic holder. - Speeds: You can adjust the blinking speeds! - Colours: Selection of colours to choose from.
