However, when the road is wet, which has been often this fall, during my morning dark ride along the unlit street for 3km (2mi), even my bright light is not sufficient to ride at normal speed (~20kmh/12mph). For that reason, I have, over the past 2 weeks, ridden a different route in the morning along lit residential streets.
