I'm embarrassed asking this question but has anyone any tips on how to clip in the H1 retainer clips at the hinged end? I replaced headlights in my car and accidentally popped out the hinged side of the bulb retainer clip and for the life of me, I can't seem to navigate it back into place? Thanks :-) 

Eventually got this sorted - for anyone this happens to the bracket that holds the retainer clip and closed with all the moving around. Try lift it slights by sliding a nail or wire through the bracket and pull gently up with pliers to widen the gap slightly.
