The UEGO gauge features an air/fuel ratio (AFR) reading, accurate to 0.1; 24 color-coated LED lights act as a needle, sweeping from green to red along the outside of the gauge, giving the driver instant feedback on the current AFR condition. It also brightens and dims automatically, according to ambient light.
