Mining vehicle head light lamp failure rates??? Is it high?

[robsalv]

Prior apology for cross posting.

I'm an engineer in petrochem industry - not that that is relevant.

Somehow, a mate and I got into a "discussion" about light bulb filament design and whether you needed a different designed globe for the high vibration and continuous lighting service of a 24hr/day mining operation vehicle compared to a normal everyday road going vehicle.

So that made me wonder, what is the MTBF of headlamps for mining vehicles?? Days, weeks, years? And do they have a special globe design?

Thanks in advance.

Cheers

Rob

U/Grnd typical life ave 24 hours-- depends on operator
usage.......20 yrs back, we used to remount with filament
vertical - extended life to months rather than days.
