The thing I find incredible is that, with usually three or four
vehicles at any one time (including my current 406 and two earlier
pugs), I have not had to replace a bulb in the last ten years and,
over thirty years, might have replace three. I suppose it comes down
to the fact that most driving is done in daylight. But you would think
that the fragility of filaments and the constant bouncing around would
destroy bulbs rapidly. Now I find myself developing conspiracy
theories as to why the life of household bulbs is so short - I buy
them by the dozen. You would think the household environment, compared
to vehicle, would be looxury!

You should invest in low energy bulbs for the house. Save you a fortune in
the longer term, and ecologically sound too.

We call those Transitional Lighting because of the way they come on slowly

Ours don't. Virtually instant they are. I think the slow ones are usually
older, serpently the ones produced in the last couple of years are instant.
And there's less mercury in them than previously, less than emitted by a
coal fired power station powering an incandescent bulb.

Low-energy bulbs are good where they are usually left on. For places
with lots of on/off their life suffers. Also they seem to lose
brilliance as they get old - like us! But they have their uses.

To get the same power with a higher voltage (i.e. mains for household
bulbs), you need a higher resistance filament, which is achieved both by
it being longer and made of thinner wire. Thinner wire is inherently
more short lived and fragile, so your household bulbs are a more
delicate beast than your automotive ones!

I would begin to question a few other things here, when both go at the same
moment, it's too much of a co-incidence.
I did buy some cheap bulbs off Ebay a bit ago, both of which only lasted
less than 12 months.

I had a similar experience last year, had three go in a week, two within
24Hrs.
So I bought half a dozen spares and prepared to have the electrics checked
out.
Twelve months later I still have half a dozen spares and feeling that
perhaps coincidence as well as 'sh.t' happens.

Don't worry about only having one head light, just join what would seem to
be about the1 in 10 cars that drive up and down the A10 with only 1
headlight night after night after night.

Hi
Try switching the lights on before starting engine (just for 5 secs),
this will give them a chance to heat up before the 14v of the
alternator starts them with a bang.
(inrush current of a cold bulb is higher than inrush current of
preheated bulb -if they only blow at switch on the above may help).
Also you could check that the output voltage of alt. is not too high!
Regards
Al

Nice one Al, that sounds reasonable.
