| Oy5 - G 61120 Nov. 6, 1920 Mr. Claude Johnson - 2 The usual method of dimming headlights is to insert a resistance in the headlight circuit, but the more efficient methods are - (a) To connect the headlights in series. (b) To illuminate small auxiliary bulbs in the crown of the headlight reflector. This latter method will be seen on the Buick which we are sending over, while a similar scheme is on the Marmon. We should be glad to know whether you think that this condition can be taken care of on the new Rolls-Royce switch box.
