Ok First The HGA is just a hollow capped off cylinder. The four Alein head screws are just screwed into the cap plate, what holds it on are two large pop rivets attached to a plate inside the cylinder. The dimple is a punch mark from the hole punch used to make the cap plate, some reason the hole got flipped to the outside on this one. The outtie dimples on the PPD disks are just thin material flipped with the dimples in.
The gun lights:
The electronics in the first movie hero packs were pretty complicated. They had several Eproms on two large boards with several dip type switches which allowed changing the program used. Ever wonder why some of the packs rotate clockwise and some counter clockwise? Dip switches changed the dirrection. Our electronic board that simply blinks the four leds and does the powercell thing uses electronics that was around for many years before the movie but for some reason they used Eproms............... to run programs.
The bargraph shows the build up to full power, markings to the side show, one quarter, one half, three quarter and full power. Like on the trap, when the bargraph lights from left to right and finally the full containment light, lights, the gun's bargraph lights from bottom to top and fluctuates till full build up and the full power light, lights. Once the bargraph reaches the top it stops and remains lit. The orange light, which is not a "hat" light but a low profile indicator light, you can see the black base in some of the photos, is actually the full power indicator.
What you've been looking at all these years is actually the begining and the end of the cycle and thinking it's two separate things.

In the gozer encounter, all four guys have packs but none of them have that thrower attached. It might have been made specifically for that close-up shot. I also think it's the only thrower with a working bar graph. I noticed that this shot is the only time we see the bar graph move up and down, in all other shots where we can see the throwers turned on, the bar graph is solid orange.That's because that's the hero thrower which is intended only for close up glamour shots. It's the only one with fully functional lights and it is attached to the hero pack. The only "functional" lights the other throwers had were the white blinker by the vents, the switched vent lights and the orange hat that indicated to the production team when the flash bulbs in the ends of the tubes were spent and needed to be replaced before the next take. All other lights were full-on and static.

As to the Hero pack lights, they all had fully-lit bargraphs but only one had one that moved.
