I have a simple outdoor light connected to a switch in the hallway. When I turn on the switch, the light comes on for 2 seconds then goes out - the bulb does not blow and the fuse in the circuit breaker does not trip. What is the problem? Could it be the wiring from the switch to the light or is the fuse in the cicuit box not man enough? Any help appreciated.
I can only guess but many light cells have self test and the light will come on for few seconds on first switch on then go off so either it is faulty or is getting light from another source which is holding it in off mode.
Could be 101 other things but I would look and see if there is a sensor first.
No it is not a PIR light and there is no sensor, it is a basic £10 light which is new and takes a 60W bayonet bulb but the light is ment for outside. I have tryed all sorts of different bulbs including energy saving ones and lower wattage ones but they all go out after 2/3 seconds.
It sounds like a loose connection in the lampholder to me , as soon as any current passes through the cable it loses its continuity and goes off. Try checking all connections to and from the switch to the light and then also look at the lampholder in the fitting you may find it is not making a good connection to the pins on the lamp and when heated up breaks contact.
