Headlights cutting out / fuse block terminal replacement

[crazyspoon05]

Howdy all

My headlights have been cutting out at random intervals recently and upon removing the low beam block fuse I have noticed the fuse holder block has melted in some places so I'm assuming this is causing the lights to flicker or cut off and on

Have misplaced my Gregorys manual and was wondering how easy it is to replace individual fuse blocks (or if the whole block needs changing) in the engine bay fuse box ?

If it gets that desperate, it might be easier to cut the wires out of the fuse box and put a seperate single fuse and holder beside it in the engine bay.
