Main information
What it could mean
A light that turns off on its own intermittently usually comes from a poor contact at the light point, the switch, or the circuit itself.
Safety first
Note if it always happens at the same moment (for example, when another appliance switches on) or completely randomly; helps with diagnosis.
Next step
If the pattern coincides with another appliance being used, it could be a one-off voltage dip; if random, it usually points to a loose connection.
Frequently asked questions
Could it just be the bulb failing intermittently?
Yes, some faulty bulbs fail intermittently before blowing completely.
What should I note to help with diagnosis?
Whether it always happens at the same moment, what other appliances coincide, and how often it repeats.
Is this the same as flickering lights?
Related; here the light goes fully off intermittently, not just flickering.
