The batteries may have become slack in transport, please follow the steps below to reset the tension of the batteries.
Remove the clear sleeve from the batteries, (take note of how the batteries are positioned) and push the batteries out with a tool.
With batteries removed, you will see a small metal tab. Using the tool, insert it under the bottom hoop and flex tab inwards. The end result, the batteries will be held much tighter.
Replace batteries - negative end should point towards LED.
