Narrative:

MEL 33-1-xy was effective. Aircraft flew for nine days with this MEL; and transited at least eight maintenance bases in the previous five days. In captain and first officer opinions; remaining lighting system lights may not have been sufficient to clearly illuminate all required instruments; controls; and other devices for which it is provided. Also; lighting configuration and intensity from alternate sources may not have been acceptable to the flight crew. Dispatch agreed with captain on these concerns; and provided link to maintenance. After directing captain in several unsuccessful circuit breaker resets; and without advising captain and dispatch; maintenance brought in chief pilot on call. Chief pilot did not provide safer alternatives for crew to consider in operating the aircraft. Rather; chief pilot said crew could be replaced with somebody who was willing to fly the aircraft one more leg. Chief pilot also stated that nine other captains operated that aircraft; and implied I should; as well. After thoroughly evaluating cockpit lighting conditions during engine start and taxi; crew decided it could safely operate aircraft. Crew used overhead flood light in combination with bulkhead lighting to operate the area affected by MEL; however; lighting in many areas was very marginal.
