That's a very typical "TIRE VALVE STEM CAP" as they are called. They now come in all kinds of colors and with lights even and are a standard threaded cap for tires.

Inside is called a schrader valve which is holding air pressure and can be replaced and adjusted if leaking there. If you just need the caps - ask any place that installs tires and you would probably get several for free!

That pic shows the schrader valve inside,

Yes - They make caps with tiny batteries that turn on lights (LED lights right on cap) triggered when moving along called "fireflies" and other amusing tire valve caps - some very funtional that change color when pressure is too low!

It's still worth checking pressure normally and the other toys are unnecessary. A plain cap should be there if just to keep water and dirt away from that schrader valve.

Know that the caps alone should not be counted on to hold the tire pressure in ordinary caps,
