Narrative:
I was delivering an small aircraft for a dealer out of tulsa, ok. Upon landing at dal was unable to get a visible green for the landing gear, made 2 approachs trying bulbs and dimming lights and felt that I had a light but only too dim to see well during the day. Upon landing I had aircraft looked at and maintenance found that there was a problem with the rheostat. Gear indicator operated normally after this. 2 hours later took a buyer for demonstration ride and upon returning to dal for landing was unable to get gear down and confirmed this both with a nacelle mirror and tower fly-by. Left pattern to ponder and correct condition. Went through emergency procedures which included disengaging gear motor and manually trying to lower gear. Found that circuit breaker out and spent approximately 30 mins reengaging gear motor. Gear was then lowered mechanically. After landing no definite answer was found, other than an awl tool was found to have been left in the gear well by a previous mechanic, however this was not proven to be the problem. This aircraft was in full compliance with all far's, as well as was PIC.
