The newly redesigned Sonic Informer, model SA 101 will alert you by flashing any attached lamp. The lamp plugged into the SA 101 can only be used for signaling. It is ideal for use in kitchens, bathrooms, or anywhere an extra lamp is not needed for lighting. There is also an indicator light to remind you to turn on the attached lamp. A Super Shaker SS 120V bed vibrator can also be plugged into the SA 101.
