    Hi all just moved into new home and putting up a light over the sink in bathroom. I got an IP21 light which just has a brown and blue wire but coming out of the wall in the bathroom is 2 blue and 1 brown with a piece of the cable bent back. Tried all combinations and best i can get is that the light just flashes on and off. There is 2 switches outside the bathroom one for the main bathroom lights and the other i presumed was for this other light but it only flashes when i turn on the main light switch.
    Head done in! any help hugely appreciated!
    Thanks

    Bunter the two blues are two nuetrals which should be connected together with the blue from your light and connect the brown with your brown. If it is switched from the door then the brown should become live when switched (phase tester). Is it a shaver light by the way and does it have a pull chord??

    Thanks for the reply. The brown isnt live at all even when switched but i do get a positive on the phase tester on one of the blues. Its just a basic light for over the bathroom sink, im thinking at this stage that the switch is wired wrong as with all the combinations the light will never come but when i turn on main lights it will flash.

    The phase tester lighting up is due to the "broken neutral". Both blue wires should be joined. I take it that they were joined before you started the job?

    Yes as the other post says the blue is live because of a back feed on a broken nuetral. the two when joined together will not be live you will find. If the brown is not live when switched on it may not have been connected in the back of the switch. If you open up the switch and find a wire not connected then connect it into the terminal marked L1. Plus make sure there is a link of wire linking the two terminals marked com. When the switch is on you should have a phase going out on L1 of your mirror switch which should mean you have a phase at the brown at your lighting point. Turn off power if you have to work on anything if your not sure. Also the reason I asked if it was a shaver light was because it wont work unless the cover/shade is on and sometimes the copper strips on each side may need slight adjusting.
