I use heat resistant ceramic wire connectors and related connections but these connectors keep failing. Where the lamp pins touch, they almost burn and stop working. I can open the fixture and shake the bulb in the socket, which eventually cracks like corrosion from the "soot" and lights up, but that's temporary. I've replaced three of them on the same device and it's going on. They are made for MR16 bulbs so they need to be able to withstand the heat of MR16 bulbs.
