I have to say, in a moment of stupidness, it looked safe and decided to try turning the remaining bulb while the light was on - thinking nothing would happen, well, til *BANG* - plunged in complete darkness with only a massive bright light around my thumb. My first thought was feck, what have I done, the next bit was, what do I do ? do I earth myself? do I run my thumb under a tap?
Luckily, due to the fuse and wiring of the flat, it had done the tripswitch in - stopping me from doing any further harm.
Light still not fixed - thumb throbbing slightly!
