A solar energy powered flashing device includes a light-transmitting, dome-like cover inside which a high efficiency solar energy plate and a circuit board connected to the solar energy plate are received and fixed by a bottom plate attached to the cover. The circuit board has a light emitting diode, a rechargeable cell for driving the light emitting diode and an integrated circuit for controlling the light emitting diode to flash. The cover has a plurality of substantially flat, segmented inside faces, each of which defines a focusing lens with the dome-like outside configuration of the cover for concentrating light and the inside faces have rhombic refractive notches formed thereon. The bottom plate is provided with reflective coatings to reflect light missing the solar energy plate back thereto.
