Narrative:

Taxiing for takeoff to 3C at dtw. Following a small twin noticed no tail lights nor rotating beacon on the twin. I keyed the microphone and said to the light twin, 'aircraft number one for 3C should turn some lights on'. He didn't acknowledge but tower answered and said he was on a different frequency. Then they relayed my comment, but no more lights appeared. The twin was cleared into position. I repeated my statement to the tower, but they did not answer. Instead they cleared him for takeoff. At that point a strobe appeared from the right wing only, and he took off. I told the tower that I had tried to advise them that an airplane was about to depart with insufficient lighting, but they had cleared him to take off anyway. Their reply was that the twin pilot had told them all his light switches were on. My answer to that was that I was outside looking at him, and that his switches may have been on, but that was all.
