Accessories typically identify themselves by briefly doing something the user can see or hear. The behavior is specific to the device. For example, a light bulb might identify itself by briefly turning on if it is currently off, or by briefly dimming if it is currently on. This can help a user pinpoint one device among several that are similar.
