Why wont your new solar sidewalk light stay on at night?

If your new solar sidewalk light won't stay on at night, it could be due to insufficient sunlight exposure during the day, preventing the battery from fully charging. Additionally, a dirty solar panel can hinder the light's ability to absorb sunlight. Other possible issues include a faulty battery or connections, or the light may be set to a mode that limits its nighttime operation. Lastly, check if the light has an automatic on/off feature that might need adjustment.
