Can't find led strip with 2 wires

Hi… im new at this… and trying to find a led light strip 5V component … i find this (WS2812 RGB LED strip.fzpz on WS2812 RGB LED strip & matrix but has 3 wires… the one i have has 2 wires … or i can use the other some how?

Thanks

Presumably this is a single color led strip (the listed ones are all rgb.) You probably need a custom part which would require the data sheet for the led strip you have (or the web site for the strip you have which may have the necessary information to make a part.)
