Probably simple but driving me mad

I'm trying to fit the bulb holder assembly (three prongs) into the reflector of the headlamp, it's like a chinese puzzle, I can get one or two prongs in to the slots but not all three no matter what I try.

It's probably very simple when you know how, but I don't.....arghhhh

Help!!!!

barnsy,
Is the reflector or socket aftermarket?
read this about the bulbs.

I'm just trying to get the old style (new aftermarket) bulb holder assembly in to the reflector (new aftermarket). when you look at the lense you have like a cat's head hole in the middle that the bulb holder fits into with the three bulb holder pins fixing thru the cats ears and chin, I nkow best I can explain....

I can get one or two pins fitted but not all three at the same time...

Thanks

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.

Hmmm, OK I will try again, that's basically what I have been doing, maybe I need to be alittle more forceful.

Thx

Sounds like the Aftermarket parts need a little rework!
File to fit?
Does the bulb fit in the Socket?
I have no experiance with any aftermarket goods, prefer to rebuild original parts.

OK after talking to a friend he suggested bending the last pin to make it fit. I did this and it's now put together and working fine. I hate applying force because I normally break something, but couldn't see any other way of getting the damn thing together.
