It's probably clear to you by now, - they don't exist, i.e. not available commercially - actually the "2 filament split bulb" really doesn't exist, because:

The ones in the videos are made out of 2 white LEDs and a resistor, soldered on the base of an old bulb(you will have to crack and remove the hollow glass part, and the filament and the little glass ball under it) and then solder 2 LEDs in parallel (but opposite polarity) with a resistor (forgot how many ohms, like 500, see 2nd video) in series onto the two leftover bulb wires. An hour or so of tinkering. A little piece of thin cardboard in between them takes care of the left/right half of the lens being lit.

The two LEDS set up this way take advantage of the current going opposite ways when left vs. right turn signals are activated. For beginners, LED = Light Emitting Diode, where Diode = electric one-way valve.
