I'd give laser pointers to Neanderthals. Even if they did figure out some useful application for them (maybe hunting?) they'd run out of batteries eventually.

I would take a portable CD player, place a CD with Rick Astley's Never Gonna Give You Up on it playing backwards, hook up solar panels, remove the ability to shut it on/off, and set it up a circuit that will:

As the device solar charges, keep it off until some voltage threshold is exceeded
Once the voltage is high enough, start a random timer (8 - 100 hours), so that it is not immediately obvious that the sun activated the device
When the timer ends, turn the music on on repeat mode
Sometimes turn the music off at random, and then turn it on again at random after a long delay, so that in some cases you can have turn 'ON' events without the device being exposed to the sun
When the voltage drops below a low threshold, turn the device off until it is charged again
