 The turtle charity asked the UK company Fishtek Marine to design a new net light that tackled the fishermen's issues. Powered by just two AA batteries, it was slimmer and lighter and could be sewn onto the net ropes. At $8 per light, it was also just a third of the cost of the original light. We've just scooped up a bucket of water from the harbour, some salty water, and now we've put in this light with the batteries. Yeah, it's kind of flashing quickly.
