Lamp was pulsing when plugged into a certain circuit I tested the receptacles voltage and it was varying often and quickly Locate and repair short and or loose wire in circuit Took apart outlets and 3 gang switch plate by the front door and found loose connections and loose screws on devices. Respliced inside the 3 gang switch box and tightened screws on the outlet under front window, to the right of the tv and to the left of the tv in the living room I gave the customer options if this issue happens again later down the road
