The momentary switch triggers the audio. And the audio makes the LED flicker.

I wired a second led to a speaker + and - and it did as you said flickering to the audio. However it does glow when the battery is hooked up like it’s getting power

You could use a double-pole momentary switch and route the LED circuit through one pole of it.

Other than that, you would need some additional circuitry to create the flicker.

Thanks I really appreciate all your help with this
Would that be a double pole single throw? Or double pole double throw?

Either will work. You only need single throw. But you can easily ignore the NC pins on a double-throw switch.

Is that double-pole? Can't see a second row of pins from this angle.

It has 3 pins I wired the switch to the C pin and the ON pin. Was wondering if the NC could be used for the flickering led

No. You need a double pole switch.

That should work. You would use the C and NO on one side to connect between the laser and GND.
Then use the C and NO from the other side to connect between the LED and the '-' speaker terminal.

Do you know if you have a switch like this being small that could handle 3amp? Is there such a thing?

I don't know of any. To handle high current, a switch needs to have contacts that are large enough to handle the current without overheating. And enough room to separate the contacts to prevent arcing when the switch is opened. That is just not possible in a tiny switch.
