I can't say I've previously heard of that being done with automotive
bulbs, but I do know that some pinball guys who do this. After a couple of
lamps go out, they will replace them all at the same time because it
usually isn't easy to change them, and once the lamps reach a certain
number of power on hours, they start failing more and more frequently.
