ORIGINAL DIPPING HEAD LIGHTS. X4555 Mr. Royce is bringing the matter of dipping head lights of RR. design, and would like to know whether you have a car on which they are fitted that we could again submit to Sales. It will be remembered their criticisms were their dislike of rope operation, and a coil spring round the torsion shaft (not very important features). On the model we saw however the angle of dip was insufficient, and we think a dip angle which moves the top rim of the lamp 2¼" forwards should be provided, as this is what Barkers give with their design.
