What is this?

So I work in a store and we have a tons of cardboard displays that have flashing lights. one broke, I promise I didn't do it and this is what is inside it. I'm thinking I could use it to have some flashing nav lights in my next build but what is it? does the little board make it flash or is it a flashing LED?

That is a large LED Strobe light the large circular item on the back is a capacitor which makes the light flash by releasing the electricity all at once.

So what are the possibilities. First we know it's driven by a CR2032 battery which is 3 volts so I could attach wires to those leads and power it from an outside wire. I could place it in a saucer section and attach fiber optics to the LED that is on it.

Could I do something more out of the box such as switching the LED to a transistor and drive several LEDs?

I would say you can do with it what you want but you will need an external; power source if you want to enclose the it or you will need to have a way to access the unit to change the battery.

Well, this is a nice COB chip. The black goop houses a small circuit or microprocessor drawing enough power only to light the White LED.

Look at the second solder pads next to L1. Could be for another LED but I am not so sure, yet its a high possibility. But you must make sure the LED is correctly soldered in.

Alternatively, you can stick the multimeter probes in there and see if the needle fluctuates. If it does, this would be good news.
