Backpack LED question, help?
So I got this backpack from Sports Direct, from the Hot Tuna brand.
It lights up when someone shakes it or touches somewhere specific.
But what I want to know is how do I recharge the LEDS inside or replace them, are they solar powered or something? I don't know.

Neither do we.
You own it and can examine it. We don’t and cannot.
But if you look carefully, following the LED wiring, you should find a plastic box somewhere. That will contain the LED power supply and it will usually be a pair of button cells (typically LR44 also known as 357) or a single coin battery, typically a CR2032/CR2024/CR2016 (all three are 20mm diameter 3v cells, but with a thickness of 3.2mm/2.4mm/1.6mm).
It’s highly unlikely to be solar powered unless you can see an obvious solar cell on your bag.

maybe there is soldering trouble.on its pcb....
a crack around the joint.....
disassemble it .. use a magnifier to find the bad joint...
