Anyone know how to remove the "glass" from the wing mirror light?

mine has a tiny crack and is discoloured from water getting in. Will get it fixed eventually but its a long treck to the Stealers and I would like to give it a cleam meantime.

I think it's a sealed unit, as the lights are LEDs, so it should never need to be taken off.

Mine was changed before, condensation inside. The light is a complete sealed unit. I think the mirror just pops out but I was told they are very fragile and easy to break, I think I'd leave it and just get dealer to replace it rather than having to pay for broken mirror aswell.

ok, cheers guys
