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

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

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

(OP)
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.
