Black-Out Light, But Is It Luxor?

Here's a bit of a mystery... Looks like this was designed to be a black-out light for use during WW2. But is it a Luxor? Nothing about the design or construction looks familiar. Note the unique mounting bracket at the bottom... I wonder what size this is? The slot says "Agree____ Luxor", but does that mean the maker was Agree, and the model name is Luxor? At first I thought the black-out hood was bent, but note how the bottom cuts-in to allow more light to reach the road in front of the wheel. I may try to buy it (French eBay), since it would make a fanciful addition to the collection.
