Lights can blow due to various reasons, primarily when the filament inside an incandescent bulb breaks or when the gas in a fluorescent bulb depletes. This can occur due to electrical surges, overheating, or age-related wear. In some cases, a faulty socket or wiring issues can also lead to a blown light. When a light blows, it often results in a sudden loss of illumination and may cause a popping sound or flickering before failure.
