Since I have been asked about fixing headlights I though I would offer my solution and pictures.
I used were Marchal headlights. The locating tabs on the lights were drilled out and tapped to M6 so that I could adjust the lights from the front. The M6 bolts were located on the fibreglass using 2 washers, a nylock nut and a rubber O ring to create friction. (bolt./ washer/ fibreglass/ o-ring/ washer/ nylock) .The outside bolt in the pictures.
is button head due to UK IVA rules.
