Yes, the socket looks crimped into the reflector housing, I think ok not loose but I will take out and check better. There is a ground connection spade off the side of the socket to housing joint, I will clean that up. Now that the plated finish (zinc? chrome?) has long gone, what would you use to hold back further corrosion? Dielectric grease is an insulator so great at not shorting stuff out, but is it ok between the bulb bayonet pins and the socket (where we need contact)? This is what most folk use?
