In the FWIW department, I popped over to the motor pool last week to take a look at the LED headlights being ordered/installed by Uncle Sam. I wasn’t able to look in depth at a loose lamp because as luck would have it the power was out, but the two things that I did notice are relevant to points mentioned in the thread. First, the mounting ring appears to be integral to the assembly with the face of the lens extending around 1/2-3/4” forward of the ring. Secondly and likely because of that, the shape of the lamp body is shallow enough that it appears they would fit in the original bucket.
I also have bought a pair of $55 7” lamps as an experiment (I’ve got 4 vehicles that use 7” round dual beam lamps) and their construction shape is so deep that the buckets will have to be cut and/or reshaped to install. Next week I’m hoping to identify the manufacturer and part number of the military lamps so those who choose to can go that route.
