Coming from someone who's never done this before, do you guys have any guides/tips on how to replace the entire headlamp unit (not the bulb) for Freelander 2003 model? I mean, will it involve removing the bumper (I hope not)? Thanks heaps!

You might get it done if you partially remove bumper ( remove top and side fixings and allow to fold forward, (not a difficult job even for a beginner, (you have to start somewhere) Removal is two bolts and one nut away if I remember right .
