The way the tech works is the camera in the glasses itself is looking for the extra light coming from the LED, which is of a very specific frequency. If the light is not picked up by the camera within the first second of video, then the glasses are disabled. In this way, you can't disable the light, or cover it with tape, or drill it, or anything else - because if the camera can not see it, then the glasses shut off
