The old overhead light had one bulb, and it's a 1974 house. I matched black wires to black wires for the two bulbs, and the white wires to the white wires. The light goes on but does not go off when I flip the light switch down. Also, the old fixture had its black wire attached to a reddish/pink wire, and the white one was attached to the white. So, I tried one of the bulbs with black and black first (and black and black with the other). No go. Then I tried one bulb with black and red (and black and black on the other). Still no go.
