Abstract
A lighted toothbrush includes a handle housing with toothbrush components mounted within the internal cavity, including a power source, a printed circuit board, and a plurality of light emitting diodes (LEDs). The LEDs are mounted to the printed circuit board at generally the same position along the longitudinal length of the circuit board, with a first one of the LEDs mounted to the first surface of the printed circuit board, and a second one of the LEDs mounted to the second surface of the printed circuit board. A light ring formed of a light transmissive material is positioned on the handle housing adjacent the first and second ones of the plurality of LEDs, wherein light from the first LED is visible through the light ring at a first circumferential position on the handle housing and light from the second LED is visible through the light ring at a second circumferential position on the handle housing.
