Abstract:

The purpose of the report is to investigate the effect of filtered red light on the dark adaptation of tank crews and to determine the adequacy of the illumination provided. The present interior illumination in M-4 tanks causes loss of dark adaptation and lowers the efficiency of night vision. Filtered red light of the characteristics specified is superior to the present lighting in preserving dark adaptation. Recommendations made are that ten M-4 medium tanks be equipped with red filters and these tanks be used in night problems by a field unit to determine the adequacy of lighting under a variety of conditions.
