Well I came onto the Forum after noticing a photo posted by Great War Truck of a vehicle with Lucas lights. I was searching for Lucas rear lights for my 1902 Toledo steam car--still am--on Google and noticed that he was asking what make the headlights were in his posted photo. I managed to answer the question as I have one of them in the garage! It is a Lucas LoriLite. I had bought it for my steamer as it was period but it is too heavy. So cross Forum interests can produce results where anything to do with vehicles of a particular period are likely to have contemporary fittings that went on a number of types of vehicles, steam or petrol, military or civilian.
