Bugger just failed. Tonights journey home took an hour (inc 15 minutes
with the engine off at a level crossing) but with the headlights on
for all the journey apart from the level crossing wait.

No heater on, no radio on and just an occasional use of the wipers.

It's a 65Ah battery in a diesel van and the battery still has some
power in it now that I am back home - enough to restart the van
without any problems.

The problem is I cannot easily get the alternator changed until Monday
so the 8A battery charger will be on overnight and I need the van for
the next 3 days. Recharging at work is not a problem.

Not for long. wifes car lost its headlights after less than an hour of
being towed.

Front wheel drive van?

Conventional filament bulbs would pull about 11-12 amps but halogens?

headlamps have used halogens for very long time. My 1972 Cortina had them -
55w each
