摘要: A combination dual intensity signal lamp having a constant intensity control filament, a two-position switch actuated by the energization of the control filament to a second position and actuated by the deenergization of the first filament to a first position and a dual intensity signal lamp circuit containing the switch which connects the circuit for a high-intensity mode of operation in the first position and for a low-intensity mode of operation in the second position.
