How do I remove headlight assembly on 355?

I got as far as removing the headlight cover, but then the manual says I should remove the headlight assembly from the retaining pins. How do I do that? I see nothing to turn, push, pull, squeeze or anything else. I tried just pulling it loose by getting some fingers behind it, but that seemed to do nothing. Does anyone know How I proceed without breaking something that I will have to buy from FNA at 10 times the usual cost?
