ABSTRACT:
An intermittent low intensity light source that is switched on by a drive signal is enhanced by a high intensity light source. The high intensity light source is coupled with the low intensity light source so that at least some light from both sources is projected in a desired direction. The high intensity light source has a brightness or intensity that significantly exceeds that of the low intensity light source. A pulse power source is connected to the high intensity light source and made responsive to the drive signal for pulsing the high intensity light source to emit a brief light pulse before the low intensity light source achieves any substantial precentage of its peak intensity, the light pulse occurring in such close time proximity to the peak intensity of the low intensity light source that persistence of vision in the human eye causes the two light sources blend together visually.
