ABSTRACT:
A street crossing signal for the visually impaired is disclosed. The signal acts cooperatively with the traffic signals to provide a tactile indication of the proper time to cross a street. A vibrator unit is retained relative to a panel having an indicator window therethrough which allows contact with the vibrator unit. The vibrator unit is retained relative to the panel and frame so that vibration of the unit is not transferred to the panel or the frame.
