Hahaha.
I had prepared my original post as if the positive was being pulsed which has its own set of problems under that schematic. Then when I noticed your +/- on your video I changed it over to make if more relevant.
But, if the positive was pulsed, the same general problem is the primary of your transformer is probably just shorting out the battery to zero volts at each pulse leaving nothing for the bulbs. For now just try other primaries or even secondaries with more turns. Or, what frequency range can you pulse since you may have to go higher if the primary inductance is so low.
Also if the positive was on the switch side you would still need a zenor diode from the bulb pointing to the feed. The zenor will keep out power from the feed to the bulb up to a certain voltage making it available only to the primary and anything above that will drain to the bulb during flyback, pulse off.
This little circuit is good because it also helps show how if you consider electricity as flowing in one direction, it should never work. it should also show how we reinforce the electron travel model by saying that flyback is an outside field that miraculously jumps back into the coil to produce that peak voltage at pulse off. Since the electrons in one direction cannot do it on their own they needed to add the field collapse construct so EEers would have something to grasp onto regardless of the logic base going against it.
OK, let's say you just took a transformer and just shorted the thick primary leads directly onto the battery. Nine out of ten times the primary will eventually blow near the center winds. Rarely will it blow near the end turns. Why? Why should it blow anywhere if electricity is traveling in one direction then the stresses should be equal and dispersed throughout the primary? That never makes sense. But if DC feeds are actually both feeding both polarities into the circuit, meeting at coil center as the war of potentials fights it out while they get hot then it is our unconscious use of the diode that relegates and enforces the directional thought process of our present electrical concepts. Especially when our diodes only stop the positive from conveying back into the positive feed. We created our own play pen with the fences already set up to keep us in limbo. So where is the negative diode? None around. Why can you make a positive diode and not a negative diode? No answer ever given.
So if our electricity travels as electrons in a wire, why should the electron care about polarity while it is traveling in the wire? How are positive electrons and negative electrons possible when all they are doing is traveling in a wire? hahaha Basic EE is in trouble. Yes our systems work but we still don't know why at the atomic level.
But if you stop and consider that the battery voltage has two polarities that feed, but more appropriately convey, I'll say "forward" for simplicity, into the circuit up to the central point of the circuit which in this instance is either the center of the bulbs and the center of the primary, since both are in parallel, then look at how the diode holds back only the positive conveying forward, you will see that;
1) if the negative is pulsed, the two diodes on the positive of the bulb are useless other then acting like resistors. The bottom diode between the positive line and the bulb should be a zenor type rated at the applied voltage or slightly less.
2) if the positive is being pulsed under that same circuit, there should still be a top zenor diode required between the feed and the bulb.
OK, if you removed the transformer can your pulse light up the bulbs? If not take one bulb off and try again. Can it light up that one bulb? That would be another place to start as well.
