Hella fog lights

[Figaro]

Hi all, I've presently got my front bumper off for painting, (2003 Hymer B544 A class).
One of the fog light lenses is a little hazy on the inside and I'd like to clean it before replacing but I can't find any way of removing the glass or even replacing the bulb if that were necessary.
It's one of the 90mm units, not sure if it has a name.
Unit is removed and on a bench so should be an easy job.....if only
I looked on Hella website but couldn't find any info.
Anyone know how it dismantles ?
TIA

Not certain but I think they are a sealed unit.
Full replacement required.

You might be correct, I see no way of getting apart.
Rarely drive Moho at night anyway so I'll just refit.
Thanks

You need to warm the glue and use a sharp pointed blade I used a scalpel to get as much of the glue out between the glass and metal housing then heat it up again and gently prise the glass away from the housing with different size flat screwdrivers
