Abstract
The present invention provides an indicator system for an appliance to notify an appliance operator that an operable temperature is reached by an element of the appliance. The indicator system comprises a light source that provides light to a linear light enhancer. The linear light enhancer transmits light from the light source along the length of the linear light enhancer, to increase the ability of an appliance operator to observe the light from the light source. The light enhancer is an optical fiber or a light tube. The invention is also directed to the incorporation of such indicator systems in appliances that require a heating period, such as for example, laminators.
