Outdoor tree lights

[Nicos]

Just wondering if anyone knows whether the bulbs break in the frost???
So far they've been OK- and we've been down to -10C- if it gets any colder, should I leave them on overnight?( At the moment they are lit from 4.30- 10.30pm)
They're just the normal size little bulbs.
Has anyone had any experience of them shattering in the frost???

What do you think???

Your critical time I would think is on switch on and on switch off, then the glass either heats rapidly or cools rapidly. I don't believe the cold will bother them if they are off. The gas will get cold inside but heyho, I don't think it will get cold enough by you to be a problem
