Note all the later model cars running around with burnt out lamps (not LED's, a different story altogether regarding solder joints and high temp LED's), and yet I bet there are 1958 Chevy's with original bulbs all around the car. I never replace the old copper bulbs in vintage units if they are still good, as they will outlast any new bulb.
I have heard some tube types say the "quality" of the parts/spotwelds and the purity of the vacuum itself is not a good as it was before Solid State. Could be the same with today's lame ass bulbs.
