Cyclist visibility at night: perceptions of visibility do not necessarily match reality.

Visibility limitations make cycling at night particularly dangerous. The authors previously reported cyclists' perceptions of their own visibility at night and identified clothing configurations that made them feel visible.

The findings suggest that reflective ankle and knee markings are particularly valuable at night, while fluorescent clothing is not. (a).
