What are the odds that a 2009 Aveo, with 5500 miles has a low fuel light burned out?

It was on when i left for my test drive. That is the last time i saw it. I drove home the other night with only an 1/8 of a tank. I was about 60 miles form home.. Luckily i didn't run out of gas. but i have been wondering when the light should come on. It was below the E line, but not to the E, and the light never came on. It took 11.9 gallons to fill it.

so my question is, and i suppose this need to be an American car only cause according to my owners manual canada has different gauges, where is your fuel gauge needle when the light comes on? The book also said the light should come on with 1.6 or 1.7 gallons left in the tank, but that the tank was 12.something gallons (i forget now). So if i put almost 12 gallons in it, the light should have come on..
