A methodology, for night vision equipment, includes enabling an automatic brightness control (ABC) procedure for a light intensifier having a photocathode that automatically selects a voltage to be applied to the photocathode, sensing current being drawn by the anode, when the current being drawn by the anode exceeds a predetermined threshold, shutting down the photocathode, disabling the ABC procedure, and storing, as a stored voltage value, a value of a voltage that had been selected by the ABC procedure when the current exceeded the predetermined threshold. After a first predetermined period of time, applying a voltage to the photocathode in accordance with the stored voltage value, and after a second predetermined period of time re-enabling the ABC procedure and selecting the stored voltage value as the voltage to be applied to the photocathode.
