it comes on to tell you when to shift for best fuel economy

Standard shift or automatic.
If you are referring to the shift position indicator located next to the shift lever - YES, it is supposed to be illuminated when the headlights (not the DRL's) are activated.
On a 2007 Ford Focus : That is the " upshift " light To maximize fuel economy , when the light comes on shift to the next higher gear
bulb burned out; fuse/circuit breaker open
Sometimes when used to driving manual transmissions, we forget to press the brake pedal to release the safety so we can shift the automatic into gear. It will not shift out of park unless you do this.
If you have an automatic transmission. Then you do not have a shift indicator light.
try the shift sensor on the side of tranny
brake light switch above the brake pedal
Have you kept up on the filter and fluid changes? Is the fluid low?
