Its an upshift light that will light up at a certain RPM. Mine lights up when I plow through 4500RPM when the trainy is in 3rd (AOD transmission) and I think the idea is to prevent the torque converter to balloon for too long. Rumour has it if you keep it lit for a certain time, the computer will shut you down.

The picture is too small to see what you have circled, but I would assume you are seeing the upshift indicator light.

It should only come in 3rd gear at wide open throttle somewhere around 5000 rpms and should be accompanied by a chime. It's programed into the cars computer and it's telling you to lift off the throttle and upshift to avoid overheating the motor.

If ignored for more than 20 seconds it will begin cutting fuel and I think ignition timing too. You can get the upshift light deleted with a chip like the custom SCT ones that Dave Dalke sells.
