A cooktop includes an at least partially transparent surface being formed of glass or glass ceramic and having burner regions with peripheral and inner portions. Heating elements are disposed beneath the surface in the vicinity of the burner regions. A lighting apparatus visually indicates heating of the surface exceeding a predetermined temperature at which the surface is permitted to be touched. The lighting apparatus has a temperature-dependent switch thermally coupled to the surface and light devices controlled by the switch. Each of the light devices is disposed in one of the portions of a respective one of the burner regions.
