Sad Lightbulb Icon - Symbol of Creative Block or Failed Idea #3438757 (License: Personal Use)

This minimalist vector illustration depicts a classic incandescent lightbulb with a gray glass bulb, a white highlight for reflectivity, and a simple black frown inside-conveying emotional disappointment. Four short radiating lines suggest weak illumination, reinforcing the theme of diminished insight or stalled creativity. The coiled base adds visual grounding while maintaining symbolic clarity.

Commonly used in productivity blogs, UX design critiques, mental health resources, or innovation workshops to visually communicate creative stagnation, failed experiments, or discouragement during problem-solving. Matches user intent for metaphors around “idea fatigue,” “brain fog,” or “project failure.”
