What single instrument did the 1908 Ford Model T dashboard initially feature?

Answer

An ammeter

The very first automobiles required driver feedback, exemplified by the Ford Model T launched in 1908. This vehicle was intentionally minimalist in its instrumentation. Unlike later, more complex vehicles, the Model T dashboard did not initially include a speedometer, which was treated as optional equipment given the car's top speed barely exceeded 45 mph. Instead, the only dashboard instrument present was an ammeter. The ammeter serves to relay information about the battery's charging status, indicating whether the electrical system is functioning correctly by showing current flow to or from the battery.
