I changed the wall light switch a couple of days ago. It operates a spotlight with 3 x mains 40W reflector bulbs. Although the wires are coded using the old colors (red, black etc.) everything seemed to go well and it seemed to be a simple swap out of an exisiting unit.
But since changing the wall light switch, two of the spotlights have blown as I switched on. One rather noisily this morning.
Coincidence or duff wiring? I plan to re-examine the wiring. Trouble is, its dark when I get back from work, so I need the lights on!
