hi ive just changed a halogen bulb in my kitchen,nightmare couldnt do it without pulling whole fitting out & a whole load of dust into my eyeballs, ive changed the bulb but no idea how to fit the collar back on & what do i do with those 2 prongs now sticking out? See pics & thanks for any assistance, im sure its simple but why do they make it so bloody hard to change a bulb very annoying.!
