I was shopping for a new gas hob a year ago and looked at a lot of models, and I don't recall any of them having an indicator light. The safety setting on ours doesn't start continuously flowing the gas until a sensor has reached a certain temperature. If you let go of the ignition knob before that point, it all just turns off again. If you turn the knob without igniting it (i.e. bump it while cleaning), no gas flows at all.. I quite like this set up.
