Vehicle Blackout Shield.

Vehicle lighting blackouts were introduced on 1st September 1939 with the Government announcing a specification and a design for the three slot shield to be made compulsory for the offside headlight only with the other light blacked out completely. This example conforms to this standard design which was manufactured by a number of makers to fit various marques of car. Use of both lights was allowed in December 1941 - ' Two masks can be fitted and the use of both lights is recommended. The masks can be of the prescribed three-slot type made in accordance with official recommendations, or single or multi-slot proprietary types or, indeed, of any other design so long as it fulfils the specification laid down by the the law – viz., that the intensity of the beam must not exceed 2½ ft. candles at a distance of 10 ft. from the car;'
