1 second delay between lights on same switch - dangerous?
We had an electrician put two ceiling lights in the bathroom which had none. They added one new switch to control both. When I turn it on, the first ceiling light comes on immediately and a second later the second one over the tub comes on. They are not 6 feet apart. Then if I turn them off and turn them on again there is no delay the second time. But if I wait a while the whole process repeats itself.
Why is this? Is it dangerous? Do I need to call them back? They were electricians, not handymen who did this.
