Directions for dimming camera lights are not applicable

My neighbor (of many years) have complained that my backyard camera lights are too bright. She sent me a picture and it is horribly bright. How can I dim them? Most directions given don't work since I do not have a "Tap Light Brightness" option, so I'm unable to "adjust the lightness" like it says. They're upset, so now I turned my lights off except when motioned, but I'm alone, and live inner-city, and with all the crime, I really prefer my back lights on. Please help.
