Replacing the power supply on mystery grape LEDs from Goodwill

Hi, I few months back I impulse-bought these grape string lights from goodwill (I just really like grapes), but they were unmarked and came without a power supply, and no tag/markings to speak of. Since then I've bought two replacement power supplies (both 12V, one .5amp and one 1amp), and with both, the lights lit up very dimly if at all.

I was hoping someone would have advice for how to figure out what kind of power supply to get... Thanks
