Hello, wondering if anyone here might be able to advise me on what might be the cause of this lighting issue that I have in my home. The bedroom light has slighted to flicker when I switch it on. It doesn't happen every time and happens at random times. Sometimes when I turn on the switch, the light bulb will struggle to brighten itself, it would turn bright then go off then turn bright then go off - it turns on brightly after a few seconds and not instantly like it should. It seems like it's just this light in the room that does this - all the other lights in other rooms are working fine and don't have this problem. I have tried changing the light bulbs but it still does the same thing. I am wondering whether it's a faulty light fixture that needs replacing or the light switch needs replacing that is the likely culprit or something else? I thought it might have somethign to do with a surge/overload of multiple electric applicances being used at the same time but a couple of occcasions this has happened early in the morning when there are no other electrical appliances in use.
Light in room flickers when turning it on

An alternative method, might be to turn it on, then try tapping first the switch, then the light fitting. When it flickers, when you tap one of them, is likely where the issue lies.

I had it with a landing lamp, and it seems when re-wired, the electrician has simply not get the wire in the terminal under the screw, and it was just touching. Nothing looked wrong, but slight tug on wire showed it to be loose. Found some years after the rewire.
Standard switch, or dimmer?. Standard filament lamp, or LED?
Just to add to that a little, vibration form nearby over time can cause connections to tighten/slacken to some extent too so if its under a floorboard to a romm above it and it gets some traffic then that too can be a source of change. Whether filament lamps or fluorescent lamps (Including CFLs) or LED then they can all have problems with this and usually show up in slightly different ways too.
But in any event a connection not quite right is your first port of call . another thing to consider can sometimes be capacitive coupling sometimes adding a strobe type effect too. You might even have a dodgy switch.
Tap tap tap nearby a switch or light fitting might or might not give a clue or two.
intermitent problems can be difficult to track down but once you do then it all makes sense.
Dirty switch contacts or lampholders or overheated parts can play a part too.
Just hoping what everybody has said leads you to some clues
The main thin is, before you open any thing, confirm absolutely dead and locked firmly off - Electric shocks are never your friend!
The tug on the wires, after terminating, to make certain - is normally the final check that any competent installer should make.

Agreed, but it seems they didn't as screw tight, but wire loose, I know vibration can cause screws to become loose, but then to tighten back up again seems to be pushing it somewhat.

I have had springs fail in BA22d lamp holders, but not since moving to LED.
