Narrative:

Mistook taxiway O-9 for taxiway O-8 due to inadequate airport lighting, and joined outer taxiway at O-10 due T aircraft parked at O-9. Ground controller instructions had been taxi to runway 21R via O-8 outer. Mistook O-9 for O-8 and had to proceed north to O-10 to gain access to outer due to aircraft parked on o- 9. Unable to resolve with ground control at the time due to frequency congestion. Suggest dtw procure adequate airport lighting and another ground control frequency.
