DIY is also ok. Find a square dance speaker remote control, add a triode switch circuit, and drive a high-power infrared emitting tube. Infrared tube can buy that kind of 3W infrared LED for night vision monitoring. I suggest you don't do what you sell online. Just find a spotlight flashlight and replace the LED with infrared one.

The remote control has a button and a switch, such as signal selection or volume. Then aim at the speaker from a distance and turn on the switch to ensure that the square dance aunt can't find you.
