With a sharp knife or small flat screwdriver try to get out as much sealant as you can from
the groove between plastic headlight body and the glass (it is plastic too, but I will further
refer to it as glass)
There are three pins holding the light together (and sealant of course). Two pins at the
bottom and one on the top of the light cluster (red arrow).
Start dismantling the light from the bottom side, as bottom pins are shorter and easier to
open as the upper one. You will probably need to use wide flat screwdriver as a lever to
loosen the sealant at more places
Don’t rush or use excessive force!!!!! The headlight body isn’t made of very hard plastic
and you can scratch the glass easily too. Take you time and prise off the glass very slowly.
The sealant is very sticky and likes to smudge the glass, your hands and everything around.
When you take the headlight apart, take out the inner chromed plastic of the glass.
Clean the edge of the glass of the sealant. First mechanically, than use some solvent. I used
benzine for technical purposes and it worked quite well. You can clean the glass completely,
but be careful not to scratch it.
Clean the headlight body groove of the sealant. This hasn’t to be perfect, but you have to
make the groove wide and clean enough to be able to fill it with new sealant.
