A criticism has been made recently of our dynamo on the Phantom in France, that we do not enable the batteries still to be charged when using headlights. It is suggested that we should employ a type of dynamo such as is used by Hispano and some others I am informed, which is capable of charging the battery, as at present when touring in the day time, but when the headlamps are turned on the armature is capable of developing sufficient additional current to feed the lamps as well as carry on the good work of charging. Has such an arrangement been considered by us at all, and if so, what additional weight would be entailed in connection with the generator? Any remarks on the point would be interesting.
