    Need to cut into a mask to reveal layer

    JPSMAC Level 1

      I need to cut into a mask to reveal a layer. I have a alpha image with thousands of lights scattered around the image. I'm laying the lights layer over an image of a city to create more lights in various buildings. All I need to do is create some form of mask that when I cut into it reveals the lights below which is over the city. It's a basic question but I'm stumped. Thanks peeps.
