How to get inside the headlight assembly?

[sasha055]

Hi,
Does anyone know how to get inside the headlight assembly?

I have a clear headlight with burn marks inside. I want to open it.
Normally you sould heat it up and it will open, at least that how it worked for lexus headlights.

I tried it and it dodn'y work for boxster.

Are there any hidden screws that hold it together? there are 2 screws that hold rubber to the assembly..but they don't seem to be going deep enough to hold the assembly.

Any info is greatly appreciated, I's really want to restore it rather than selling as broken item

Thanks
Sasha
