Quoted from tfduda:And what about the poor souls in a few decades who are trying to repair the circuits in an EM that uses a 455 bulb as a delay and can’t find any incandescent 455s? How will they hack it?
I'll suggest trying the blinking circuit from the brake warning light in a LADA 2107, only with a different wiring. It works in the same way as the blinking bulbs, with a heating wire around a bimetal spring.
