Hi we have a spotlight unit in our bathroom containing 3 bulbs. Some months ago 1, then 2 of the bulbs stopped working and replacing them did not seem to work either. We are left with 1 working bulb which always flickers. It can come on, stay on anywhere between 1 second and 5 minutes and be on solid or flickering like a bloody disco. I don't think it is the switch as when it flickers I have found that if I press the bulb very slightly to the right within it's holder then it corrects the problem for a short while. The bulbs are screw ins and bizarrely they often work better when not screwed all the way in! I may see if the unit has connectors which can be bent out towards the bulb to make a better connection but I don't think they can. Does this sound like the light fitting/unit as opposed to a loose connection? Thanks in advance and I know the easy option is just to replace it but I'm no electrician so if it can be easily fixed great.
