Replacing Headlight Unit

[old son]

My off side headlight unit is fogging up and requires replacing. How difficult is this job? I can see a couple of fixings along the top of the unit and maybe a couple at the bottom. Will I need to remove the front bumper or can all the fixings be accessed from the engine bay?
Thanks

according to berlingo b9....there are 4 bolts.....also the front bumper maybe needs to be taken off......probably to get at the bottom bolts.........i don't know why....bit of a faff if u ask me..........

I've had a look from the engine bay and I cant even see the two bottom fixings!! I don't want to take the bumper off if I don't need to.

Is taking the bumper off a faff as well?

you may get away with partial bumper removal just to get at bolts

Update, I got away with partial bumper removal, off side only. Still a buggar of a job but its done. Thanks to those who responded.
