Narrative:
On approach to bfl on the localizer at approximately 8000' MSL, we observed flashing, unsequenced, random white strobe lights (no position lights). Due to the nature of the lights we both felt that they were in the distance and probably ground based military oriented. We asked approach about the lights, but by that time the aircraft was going by our left side within about 20' and was momentarily illuminated by our landing lights. We later learned that the aircraft was doing aerobatics as observed by other aircraft. This fact and the lack of position lights made the identification of the lights as an aircraft extremely difficult.
