Doubtless you saw at the Show, or have seen in the Motor Press, description of the new Lucas Dippers which claim results by dipping the reflectors instead of dipping the whole lamp. This seems to us to be a very practical and simple scheme. We are proposing to have a set of lamps on a 20 HP. Car fitted with this device, but we should be glad if you could arrange for a set to be tested at W. as well, as we always wish, as you know, for any items of this description we think we shall be called upon to supply, to have the approval of W.
