Assume you are asking about recessed lighting. There are units that have a can around where the bulb is located to keep insulation a safe distance from the heat generated by the bulb. Just cut away the insulation so the can will fit. Buy a fixture that has thermal protection and will cut off if the fixture gets too hot. Follow manufacturer's recommended installation procedures. <<>> Don't leave your ceiling vapour barrier with a break in it. At the place where you buy your fixtures ask for a vapour barrier plastic boot to go over the fixture to seal the existing barrier. The easiest method to install this boot is from the top side in the attic if possible. Make sure that you use vapour barrier adhesive tape to seal the existing barrier to the new fixture boot.
If the outlet is on an outside wall there is a plastic boot that goesaround the outlet. The purpose of this boot is to keep the vapour barrier intact. The edges of this boot are then taped to the wall vapour barrier to make a complete air seal. The insulation goes behind the outlet boot which allows the wall R value to remain the same as the rest of the wall.
