An auditory signal, such as a short burst of sound or a beep, can work among obstructions and can be heard in the dark. Olfactory signals rely on scent, which may not be easily detectable at night, visual signals rely on sight which may be hampered by obstructions and lack of light, and tactile signals rely on touch which may not be easily communicated over a distance.
