They hadn't come up with the concept of a sophistcated state-of-the-art advanced warning sysyem yet.  or as most recognize it: the yellow light

And Google is wrong.  The first modern three-way, red-yellow-green signal everyone knows was invented in 1920.    This two-color signal was merely a step on the way.

Perhaps you should read what exactly they're commemorating again.

Red clearance... Kind of hard to stop when you don't know when it will change

The key difference that Google is celebrating between the Cleveland one and the near-identical earlier ones in London is not that the operator could sit in a booth, as Vox mentions (I'm not sure if correct though) but that the lights were electric, not gas.

Automated lights were around before too long - the UK got its first in 1927.

Almost every car is running the red, unless the signal is broken and gives all approaches green simultaneously.
