Could be as simple as an iffy bulb. Process of elimination…….The circuit breakers for the house lights keeps tripping. Started yesterday & have been trying to get an electrician since. Phoned 2 yesterday & left messages on their mobile, another 2 today. One said he'd get back to me before 1.00pm, the other didn't answer so a message was left.
Later, I'll be bringing my inspection lamps in from the garage later so I have enough light in the kitchen to cook dinner.
