Ok, barnsy, Using Your terms,
Went down and pulled a Guide reflector and Socket, This is how I put them together.
My socket has a rail or bar connecting the Two closest pins on the socket.
I inserted one of these pins in What You call the "CATS EAR" Then rotated the other from the cats chin up into the other ear.
once this is done the socket must be pushed towards the ears, (The pins swivel), And the bottom pin can be angled into "CHIN SLOT"
Best I can explain!
When the bulb is inserted, Push the socket towards the reflector then install the bulb and twist it onto the pins.
