Headlights pop up on starting?..........why?

[MartinL 19]

As per the the title really, lights pop up when starting from cold and fall back with a bang, as i dont think this should happen has anyone any idea why ?

Everything else seems ok (other than ongoing hot start problem)

Low battery. Drive it more or stick it on a trickle charger.

No need to rush out to buy a new battery. First check to make sure your battery isn't being drained by the front and rear boot lights along with interior light, they sometimes stay on. Also check any other device, alarm, imobiliser or stereo?

Try charging the battery also and a trickle charger is also good.
