In the video, a man is seen using a pair of pliers to work on a light switch. He is using the pliers to adjust or fix the switch. The man appears to be focused on the task at hand, and his movements suggest that he is experienced in this type of work. The light switch is mounted on a wall, and the man is standing in front of it. The background is not clearly visible, but it appears to be an indoor setting. The man is wearing casual clothing, and there are no other people or objects in the frame. The video does not contain any dialogue or sound, so it is difficult to determine the exact nature of the work being done. However, the man's actions suggest that he is either repairing or installing the light switch.
