Reliability

Love it :-)

There was extensive research into headlights in the USA in (I think) 2008.
After exhaustive tests it was averaged out that the high beam filament should last 3 years 7 months and 14 days, where the low beam filament was 5 years 2 months and 28 days.
There was a correlation between the temperatures, which surprisingly the colder the night temperature the shorter the life, and the roughness of the road.
It also depended on the extent of driving in towns/cities and the country roads.
Based on all the results were extrapolated the expected life was 4 years 9 months and 3 days.
There was an exception, and that was the Jeep lights. The number of weeks Jeeps averaged in the workshop extended the life expectancy by a huge amount.
And, no, I don't think I can find the link.
Cheers.

Well Muzbry, Only went to get a pair of standed high beam lights for my 80 series today Not sure but I would say they are the orignial ones it is a 95, cheers Billy.

Good question.
I changed the original sealed beam units on my 1988 Hi-Ace van six months ago.
One became "unsealed" and held some free water, the other was still fine. Put 2 newies on as the currently available units are much brighter. I think the cost was about $50 on fleabay.
Motor parts are less reliable. Had to get the injectors and pump recond 3 or 4 years ago ($600 approx.)
Old girl has only done 580k, and the problem I have is to change to another vehicle will cost a lot and I don't think the trade-in will be too generous :-) Guess I'll have to try and wear it out.

Only other items are brakes, timing belts, rear main seal, (and clutch at the same time), and 1 radiator. All self serviced.

Are you talking about one of those LED things you strap to your noggin? Or a miners lamp with an incandescent bulb and powered by a lead - acid battery? Anyway my Pathfinder is plated 2001 and the headlights are original but I have replaced a rear brakelight bulb.... Cheers...... W

How long since you did a valve grind on your vehicle? Or did Rings and bearings? Strike me pink, I haven't had a puncture since 2001!

Ha ha, top thread, Muz!!!

There is an equation to work out the life of headlight globes. I don't remember it exactly but it goes something like this. "The life of a headlight globe, and it's twin, are directly related to and governed by, the importance of a future meeting, whether social or business, the timing and address of said meeting, divided by the minutes remaining before a retail outlet(ie: Supercheap/auto sparkie) closes, multiplied by the distance, in kilometres, to said retail outlet, equals driving to aforementioned meeting, with only one headlight working on low beam anyway."

Just walked outside to check the new ride.

If they have run out of halogen I've got a machine at work that can refill them for you, cost $10 to $20 depending what glode you need filling. They come up like new and last as long as your old ones.
