Hand-Drawn Light Bulb Icon

Create a high-resolution icon of [object] in a playful hand-drawn style with bold, uneven black outlines and flat, bright colors. The fills should look very imperfect and hand-colored, with some parts of the icon left uncolored and visible colors going outside the outlines. Make gaps where the color misses parts of the shape, and let the fills look quickly done with a marker or paint crayon with rough overlapping and sharp edges. Add a wobbly white outline around the icon for a sticker effect. Use a limited palette: bright yellow, dark purple, and white for contrast. Add hand-drawn accents like sparkles, dots, and motion lines. The design should be clear, clean, and vector-friendly. Use only solid colors. No blur, gradients, or textures. Background should be periwinkle color. Square aspect ratio.
