The link that says "although there is vigorous disagreement about whether 1000 days was a good technical standard or a case of planned obsolescence, a cartel did exist, and there are sources which say it was to use planned obsolescence to sell more bulbs". Inconveniently, longer-lasting bulbs emit less light, and more heat. If you remember the heat of a 100W incandescent bulb, perhaps you might see the fire hazard in encouraging bulb companies to compete on the basis of bulb life. But no matter.

This definitely demonstrates that there's a brake pad cartel, right now, doing the same thing. By implication, you see.
