Many of the modern ones are intelligent and form a self-defining mesh network to talk to their neighbours to do the 'strobe' flashing.

They can also be turned-on-and-off, have their colour switched between amber and red, and can report their battery-status wirelessly - rather than needing to be fiddled-with individually by an individual-in-a-hi-viz jacket. The electronics needed to do all this are implemented as a single resin-encapsulated 'blob' fitted to the PCB which also forms the battery-connection plate.
