I had some pics up on this a while ago, but they got deleted. So here's another guide on how to clear your es300's corners.

If you have any trouble with the directions, let me know and i can edit the page to make it easier to understand...

This mod is very essential to the look of an older Es300 -- i would highly recommend that you give it a shot...

 

Sean, that's some good work there. I wondered what happened to the pics that were in CL. Something I did though, was the last time I put the light back in to seal it up, I left it in the oven for 10 minutes. That seemed to suck the pieces together and made it really tightly sealed. I have no condensation in either headlight now...

 

You can also put black silicon in thier to seal them up. That works also.
