• Hello! The pressure sensor will beep if the pressure is too hard on your teeth from the Philips Sonicare 4100 Protective clean.

• If you brush too vigorously the pressure sensor will adjust the level of vibration. The change is immediately noticeable and obvious and there's no light involved. You can disable the pressure sensor if you like as per the included instructions. Hope that helps.
