If your Arlo camera light isn't coming on, it could indicate several issues. First, check if the camera is powered on. Ensure the battery is charged or the device is connected to a power source. Next, confirm that the camera's firmware is up-to-date and that there are no connectivity issues with your network. Sometimes, a simple reboot of the camera or the base station can resolve the problem. If the light still doesn't turn on, there might be a hardware malfunction or a more complex issue that needs professional assistance.
