Abstract:
1. A vehicle brake light having a secondary personalized illumination display comprising: a primary illumination circuit for indicating application of a brake of the vehicle wherein application of the brake causes activation of at least one illumination device of said primary illumination circuit; and a secondary illumination circuit connected to said primary illumination circuit, said secondary illumination circuit for illuminating said secondary personalized illumination display and comprising: (i) at least one personalized illumination device; (ii) an electric power storage device configured to store electric power accumulated during activation of said primary illumination circuit; (iii) a voltage sensor configured to sense voltage applied to the primary illumination circuit during activation of at least one illumination device of said primary illumination circuit; and (iv) a switch connected to the voltage sensor; wherein the voltage sensor outputs a signal corresponding to the voltage being applied to the primary illumination circuit and wherein the switch opens according to the signal to prevent the flow of power from the electric power storage device, thereby preventing electric power from reaching the personalized illumination display during activation of the primary illumination circuit, and wherein the switch closes when voltage is not applied to the primary illumination circuit.
