This easy to attach adhesive reverse alert beeper comes with sensors to assist you to reverse your car safely. It sticks on to the reversing light and activates when the reversing light comes on. When the reversing light goes off, the beeping alarm stops.

The loud beeping sound alerts pedestrians when your vehicle is reversing and helps to avoid accidentally hitting anything, including your child. 

Note - to avoid accidents in the driveway, it's best not to allow the driveway to become a play area AND always ensure you can see your child standing still away from the driveway whenever reversing.
