In the category of "I had the parts so I made it", this is an internal speaker advantedge in the shortest length possible to still have any lights at all. I was thinking about what to do with the speaker section I had and noticed I only had fluted lenses and a mini frame. I thought back to when a coworker had a lo-pro siren on a mini edge and decided to make an internal speaker advantedge version. I initially thought I would be limited to front and rear 4x3 sized strobes and I thought about doing something like this:
When I put the speaker on the frame it was obvious I had even less real-estate at the ends than I had guessed. I first tried orienting the "V" heads like they are in an early edge, back to back 2 per side, but even that didn't fit. So I took a look at my early edge-cap lightheads and saw how they surface mounted the "V" heads and went that route. The result was actually pretty decent to the front and back (great to the sides obviously). I had to run it off a remote power supply, there was no fitting anything era appropriate inside.
Is it practical? No! Was it ever actually used? Not that I know of. Would I have used it on a utility truck or ATV/golf cart? Heck yeah!
The final build looks like it could have been a custom factory job, at least I think so; all the parts are Whelen.
