Fitted a set of 4 halogen lights (all one unit) which I got from B&Q. Followed instructions for fitting to the letter. At first everything seemed OK. However find that if the living room light is switched on it flickers and if the kitchen light is on it can flicker and has gone off. Everything comes back to normal when either light in living room or kitchen is switched off and then back on.
Obviously they are on the same circuit but all connections appear correct and tight any suggestions as to why the problem seems to occur some of the time but not all the time.
