A tiltable solar disk light comprising: a disk body comprising a disk-shaped housing, the housing containing lighting components comprising solar cells for harvesting solar energy and detecting ambient light; a rechargeable battery for storing the harvested solar energy; LEDs for emitting light; a latching pushbutton switch having an ON position and an OFF position for enabling and disabling electrical power delivery to the LEDs from the battery; and wiring and driver electronics for operably connecting the solar cells, battery, switch, and LEDs and configured to deliver electrical power to the LEDs from the battery when the switch is in the ON position and the solar cells are not detecting ambient light and to cut off power to the LEDs when the switch is in the OFF position or the solar cells are detecting ambient light; the disk body further comprising a pair of pegs extending from the housing, the pegs in a co-axial arrangement to form an axis of rotation for the disk body; a frame defining a circular opening for receiving the disk body, the frame having an inner circumference around the circular opening, and two holes in the inner circumference on opposite sides of the circular opening for receiving the pair of pegs and tiltably supporting the disk body, the circular opening being sized and shaped to define a first clearance gap around the disk body to permit the disk body to tilt within the frame about the axis of rotation formed by the pegs; a landscape spike removably attached to the frame, the landscape spike configured for insertion into the ground, thereby affixing the tiltable solar disk light to the ground; characterized in that the landscape spike is connected to the frame by curved arms configured to define a second clearance gap between the spike and the frame to permit the disk body to tilt within the frame about the axis of rotation formed by the pegs. a disk body comprising a disk-shaped housing, the housing containing lighting components comprising solar cells for harvesting solar energy and detecting ambient light; a rechargeable battery for storing the harvested solar energy; LEDs for emitting light; a latching pushbutton switch having an ON position and an OFF position for enabling and disabling electrical power delivery to the LEDs from the battery; and wiring and driver electronics for operably connecting the solar cells, battery, switch, and LEDs and configured to deliver electrical power to the LEDs from the battery when the switch is in the ON position and the solar cells are not detecting ambient light and to cut off power to the LEDs when the switch is in the OFF position or the solar cells are detecting ambient light; the disk body further comprising a pair of pegs extending from the housing, the pegs in a co-axial arrangement to form an axis of rotation for the disk body; a frame defining a circular opening for receiving the disk body, the frame having an inner circumference around the circular opening, and two holes in the inner circumference on opposite sides of the circular opening for receiving the pair of pegs and tiltably supporting the disk body, the circular opening being sized and shaped to define a first clearance gap around the disk body to permit the disk body to tilt within the frame about the axis of rotation formed by the pegs; a landscape spike removably attached to the frame, the landscape spike configured for insertion into the ground, thereby affixing the tiltable solar disk light to the ground; characterized in that the landscape spike is connected to the frame by curved arms configured to define a second clearance gap between the spike and the frame to permit the disk body to tilt within the frame about the axis of rotation formed by the pegs.
