How many kilometers can a car run after the fuel gauge light comes on?

[McJackson]

When the fuel gauge yellow light comes on, most vehicles can generally run about 50 kilometers without issues. Below is more information about the car fuel gauge: 1. The fuel gauge usually has three markings: 0, 1/2, and 1, or two letters F and E at both ends. 0 and E indicate empty, 1 and F indicate full, and 1/2 indicates half a tank. 2. There are two types of car fuel gauges: analog pointer type and digital type. In analog pointer gauges, F stands for full and E for empty. In digital gauges, more illuminated bars indicate sufficient fuel, while only 1-2 bars mean low fuel level, requiring timely refueling. 3. The fuel gauge displays the fuel level through a float in the fuel tank connected to a metal rod. The end of the metal rod connected to the float is linked to a variable resistor via a movable contact. The position of the float on the fuel surface in the tank changes, which in turn alters the position on the variable resistor via the metal rod. This variable resistor is connected to the car's fuel gauge, and the movement of the gauge pointer is controlled by the amount of current passing through the variable resistor.
