Saloon rear lights

[Vossy]

Has anyone successfully dismantled a rear light unit without breaking it?

I ask because I have some dirt in the corners of mine, I took the lights out and cleaned them inside but there is still some dirt that sits along the seams that can't be removed unless I can take the unit apart.

There are a couple of lugs but my guess is that they are bonded around the edge of the unit.


The dirt isn't that bad but I see it every time I go to the car and it's annoying me now
