A light does not burn. A thing that is very hot emits light. Some light bulbs have a wire that gets hot when electricity passes through it, and so it emits light. The sun is burning gas, so it emits light.
Some insects have learned to give off light without heat. We see them at night flicking on and off to attract mates. From this we have also learned how to make light without heat. We call these things LEDs, or light-emitting diodes.

A lightbulb burns because electricity goes through a wire in the bulb. The wire gets heated by the electricity and glows as it burns. Because there is no air in the bulb, it can glow for a very long time.
