That's the weird thing. It does pop loudly, but I can still pull the darn thing back out. It also fits in flush, and right now it's seated properly (no gaps or odd angles). Just that I can't get it to lock in place. The bar doesn't come "up", only rotates 3-to-9 o'clock clockwise (9-to-3 counter). I'm thinking that it just "pops" when it hits resistance and doesn't finalize the process when it's turned.
I guess I will need to try the left headlight to compare it, just partially afraid I'll somehow mess that one up.
