1948 - Dynamo bicycle lamp production
After the war, having taken cues from employees who had been riding bicycles to work, the Sanden changed its business to develop dynamo lighting sets for bicycles. It had run a sales campaign for dynamo bicycle lamps with a trademark “Owl” shining in the darkness, and with the slogans “Second sight in the night” and “A thousand times brighter than a full moon ”. It marked a monthly production of 30 thousand units in 1953, thereby establishing itself as a permanent fixture in the dynamo bicycle lamp business sector.
