This is a solar powered emergency light and simulated fish. At first I was worried that it wouldn't light up when there was no sun (and when you were most likely to need the emergency light) but I was assured that it had a battery. I suggested that perhaps a better product would be a solar powered singing fish wall mounted trophy. I was thanked for my idea and was assured that Shenzhen TRONY Science & Technology Development Company Limited would look into it for next year. You saw it here first!
