C then A then B would light up with infinitesimally small time intervals. No human could ever directly notice these delays.

Energy emerges from the battery both in terms of a supply of electrons from the negative terminal and the deficiency of electrons at the positive terminal. These will "apply pressure to" and "remove pressure from" the adjoining wire segments in opposite directions. Such application of pressure and reduction in pressure continues around the circuit forming a small charge movement, i.e. a current. The wire and other conditions being uniform, the speed of the electricity being constant (somewhere between 50% to 99% of the speed of light in vacuum), C will feel some current first as it is nearest to the battery, and before the electricity has even begun to flow all the way around the circuit. The next nearest is A. Therefore C and A will receive earlier thermal excitation, and (all other things being equal), will start to radiate earlier than B.

Energy emerges from the battery both in terms of a supply of electrons from the negative terminal and the deficiency of electrons at the positive terminal. These will populate and deplete the adjoining wire segments in opposite directions. Such population and depletion continues around the circuit forming a charge movement, i.e. a current. The wire and other conditions being uniform, the speed of the electricity being constant (somewhere between 50% to 99% of the speed of light in vacuum), C will feel some current first as it is nearest to the battery, and before the electricity has even begun to flow all the way around the circuit.
