Multiple emitters had got them to the place where they’re replacing traffic lights with multi-HILED units that I’d expect have their own integrated step-down transformer and DC rectifier.

A lot of automobile tailights are composed of multiple LEDs.
You can usually spot them by moving your eyes rapidly past them. LEDs will leave static afterimages.
Incandescent lamps will leave a smeary trail.
They are bright enough now to do the job, and they last longer and don’t damage the plastics by overheating.
