I thought this was an urban legend that had been long put to bed - about landing light bulb life being relaed to the number of hours it is lit. Surely it was discovered long ago it is just a function of the number of airframe hours, as the aircraft vibration has far more of an impact on bulb life than for how long it is lit.
