I fixed it folks. To sum up, if the check valve on the booster becomes blocked, you not only lose power brakes, it affects the vacuum on the pedal switch, and you lose brake lights.

Hi folks. Yesterday the booster power was lost to the brakes, and the brake lights went out. Have checked known fuses, including the 10 amp on the relay under the instrument panel. Hopefully a relay? Noticed no hissing from the booster. Please help! P.S. No ABS light, and no brake light coming on on...
