Illuminated flashing toothbrush and method of use
View Patent ↗A toothbrush can include a handle and a head. At least one bristle can be attached to the head. The toothbrush can also have an illumination member, an illumination circuit and an activation device. The activation device can include two contact members fixed in a non-contact position on an outside of the handle. A method can include causing conduction between the contact members to activate the illumination circuit. The toothbrush can be an electric toothbrush. The electric toothbrush can have an illumination member positioned such that light from the illumination member can be seen by a user in a mirror facing the user.
