  • Signal light for railroads or the like
    Patent number: 6714140
    Abstract: Signal light having first and second identical electrical cells, each having the necessary capacity to last for a standard operating cycle. The cells are electrically connected by means of a bistable switch to an electronic control circuit in stable alternative and nonalternating fashion until they are individually depleted. The electronic control circuit has one output connected to one corresponding signal light and another two outputs connected to individual light indicators which are light emitting diodes respectively assigned to the first and second electrical cells and activated by the electronic control circuit when the latter detects a depletion of the electrical energy of same.
