A light that will not respond can be caused by the lamp, the fitting, a worn switch, a dimmer, paired
switching or the wider lighting circuit. A few safe observations help avoid replacing the wrong part.
Checks you can make without opening anything
If one light is out but nearby lights still work, first try the correct replacement lamp where it is
safely accessible. Switch the light off and let the lamp cool.
If it is controlled from two places, switch off that lighting circuit before changing the lamp. Match
the cap, voltage and permitted wattage.
Note whether the light works from its other normal switch and whether a dimmer flickers, cuts out or
behaves differently at certain settings.
Signs the switch needs checking
If the new lamp fails, flickers, trips the circuit, or the fitting is marked or hot, stop and book a
check.
Do not remove the switch plate. Heat, crackling, sparks, blackening, a burning smell or tripping means
stop using it and call first.
A like-for-like switch replacement is suitable only after the point, switching arrangement and
existing wiring have been checked.
