Can anybody tell me what component is used to make these LED bags glow when struck? Link below, thanks!

Could be anything from a cheap spring mounted around a metal post that flexes when struck to make contact to an accelerometer talking with a small microcontroller.

To keep cost down, it is most likely a vibration switch or something similar with a 555 timer.

Here is a couple pics, it is powered by three LR44's... I can only see the LED, and one other component that I would think is a resistor, but it is black and not color coded like a resistor...

Hard to see. Could just be a simple spring and a 555. I'm stickin with that answer for now.

Yeah, I figured it would be a 555, but I don't recognize one on there... unless it is in a different package then I remember... I'm going to take some isopropyl alcohol to the hot glue, so I can get a better look at whats going on... thanks for the reply!

I don't think Isopropyl alcohol will do anything to hot melt glue. AFAIK you need to re-melt it.

Maybe not, I haven't tried it yet, but when I did a Google search on "how to remove hot glue", most of the results said to use isopropyl alcohol

Freezer spray is what I use, it goes brittle and you can pick it off. But use with care and small amounts at a time.

Ok, here are some pics with the hot glue removed, through a magnifying lamp, any clues?

Oh no black blob syndrome. under that black blob is an IC what it does is anyones guess.
