A light guide is mounted to the second circuit board. The light guide having a body defining an opening. A light source is positioned within the opening, spaced apart from the light guide and mounted to the circuit board. A transparent adhesive layer is positioned around the light source and on the second circuit board forming water tight seal.

Electronic personal care device

A consumer appliance with a body. A cartridge removably mounted to the body. The cartridge having a surface with a first colored region and a second colored region. A control circuit positioned within the body. A first emitter that projects a first light at the first colored region and a second light at the second colored region. A first light sensor mounted the body that sends a first signal to the control circuit based on a color of light reflected from the first colored region. A second light sensor mounted to the body that sends a second signal to the control circuit based on a color of the light reflected from the second colored region.
