Stars produce light when small nuclei fuse and release energy.

In stellar cores hydrogen nuclei fuse into helium (and later heavier elements in massive stars). The fusion reactions convert a small amount of mass into energy (E = mc^2); that energy is carried out by photons (and neutrinos) and eventually escapes as the visible light we see.
