You've thought it. Standing in your backyard with the telescope, watching that unshielded security light blast photons into the sky and into your eyes. Turn Off Your Lights is the shirt that says what we're all thinking — direct, unapologetic, and completely reasonable. Beyond astronomy, it's an environmental statement: wasted light is wasted energy, disrupted ecosystems, confused wildlife, and human health impacts. This bold typographic design has protest-poster energy without being aggressive. It starts conversations about light pollution with people who've never considered it. The light switch icon adds a subtle action-oriented element. Wear it loudly. The stars will thank you. Available in 7 sizes (S–4XL) and 10 colorways.
