| x6116. C. From Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.4/MA.5.12.34. HEADLAMPS AND FOG LAMPS. Many thanks for your C.5/C.3.12.34., we agree with your remarks regarding the Lucas FT37 fog lamp but we still think that it is not as good as the Currus lamp for really dense fog driving. You will see in our Hs{Lord Ernest Hives - Chair}/Wst.3/MA.5.12.34., that I have suggested that you equip one or two cars in London with these Currus lamps to gain experience. We are of the opinion that the bi-focal dipping lamps which we are now trying out will be responded to on the road equally as good as the dip and switch to the left. This type of lamp is universally adopted on the Continent and GWH.{George W. Hancock - Head Chateauroux} informs us that such a type of lamp is acknowledged whereas our double dippers are not acknowledged in France. Hs{Lord Ernest Hives - Chair}/Wst. | ||
