Not directly train related but my daughter has changed the headlights in her car and given me the old ones.
Am I safe to use them to illuminate the garden railway (obviously connected to a car battery or 12V transformer)?

I used a head light to illuminate the railway. I connected it up to a lighthouse I had made using a 12 volt battery charger to power it.
It made the charger cycle on and off as the duty cycle cut in and out as the power used by the light is very heavy. I concluded the experiment as a failure.

Car headlights should be quite safe Mikey. I presume they are of the sealed beam type.
Just a couple of points though.
The current drain could be quite high and they wont last long even on a fully charged battery.
Typically a 100w bulb will draw about 8 amps but modern halogen types with give more light for less current.
So a pair of headlamps may only last a 3 or 4 hours on say a 60ah battery.
They could also become very hot.

It could work, but a car battery charger or other supply ( they will work well on AC also) could be done.
If your railway is French and pre 1990, be sure to use yellow lights

Are the headlight units sealed beam or do they have bulbs in Mikey? Either way there will probably be two filaments one a higher wattage than the other typically 35 dipp and 55 main beam (watts). The 100 w ones Carl refers to are actually illegal but I have used them in the past… shhhhs.
Being 12 v there perfectly safe apart from the ummph
that can be given off by a 60 a 12v battery so use an appropriate fuse in the circuit.
