Abstract
A backlit temperature control knob for water heater valves used with water heaters and more particularly to gas water heaters provides a way to read the temperature indication not previously known in the art. Some embodiments rely on a thermocouple or thermopile normally used to power a safety magnet with the pilot light system as a source of electrical energy to selectively illuminate a Light Emitting Diode (LED) which directs light through at least a portion of the knob to assist in reading the temperature indications.
