I have two Regent Motion sensor lights outside. Last night the electricity went out for about 3 seconds. Both lights came on and stayed on all night. One of them went off when the sun came up. Then other one is still on. Anyone know hoe to reset this light. It has a sensitivity knob and a switch that says test, 4 min, 12 min on the back. I do not have a switch for the lights they are wired direct. Any ideas?
