Gary, when trying to find those elusive n very dim objects, there is nothing more frustrating than having to find & adjust the dimmer control up n down. The 'flasher' can be set to very slow rate & in conjunction with your original dimmer, (set very low), work together in assisting in finding them. It can be adj to flash at a fairly long off time, eg; ~4 secs off/1 sec on & 1 sec off/1 sec on...
HTH..
