Here is a vintage, original B-L-C B-M4 Backup Light. It is similar to the Guide B-31.
That is why that is in the header. I recommend new wire with all of these old pieces. Common to find a split on these here and there.
"Fish Eye" lense is great shape! Of course, you use it for whatever your needs may be.
