I have 6 downlights that were wired into an extension I had built a couple of years ago. 2 of the halogen bulbs failed recently so I thought the bulbs needed repleacing but on checking the bulbs are fine.
However the small circular fittings (sorry i'm no electrician) that the bulbs screw into have both become slightly blackened (worryingly) and need replacing. I can't seem to find these on-line or in B&Q style outlets - basically there are 2 wires coming through each ceiling hole per downlight and I need to reconnect with new fittings.
Can someone steer me in the right direction please ?
