The Redditor mentioned that the shipment didn't include any LEDs for indicators. So I asked Wei whether he can include a few LEDs in three different colors, perhaps, red, blue and green, because I would be forced to purchase 50, 70 or even 100 of each color of LEDs otherwise. He said he will include a few LEDs in each shipment. Not sure which color will be shipped however. He clarified that 3 V, 1.8 mm or 3 mm LEDs will work. Also, he's still waiting on the re-manufactured PCBs and is hoping everything will be shipped within a week.
