The image shows a lighthouse with a green light illuminating its structure against a dark, possibly night-time, background. The lighthouse is tall and slender, with a cylindrical shape and a pointed top. The green light creates a striking contrast against the darkness, making it stand out prominently in the scene. The lighthouse appears to be located on a body of water, as suggested by the calm, dark sea visible in the background. The sky is not visible in this image, but the overall atmosphere suggests a serene and peaceful setting.
