The headlight lenses on my 99 RX300 are cloudy and yellowed. I found a 3M kit designed to clean lenses but I don't see how to get them open! I see what looks like pry points between the clear lens and the headlight body and there is a gray sealing compound that seems to glue the lens in place. That's as far as I got.

I want to remove the lens, and clean and polish, or replace. How do I get it apart?

Thanks in advance...

The 3M kit is designed to refinish the exterior of the lens. I've used that kit and it works miracles. Usually, exterior clouding/yellowing is due to long-term exposure to ultraviolet radiation and mechanical abrasion which the 3M kit deals with nicely. As for the inside, if you can get to it, it will probably clean up without a lot of effort but good luck getting there. Let us know how it plays out.

Are you suggesting I read the directions!? Horrors!

You're right, I see now. Also see that this is not a 20 minute project so it will wait for another day. I'll let you know how it goes.

MRubenzahl, it's doubtful you will have to open up your light units to clean inside. Most of the haze is likely on the outside as it was on my 2000 LS400. You are going to be amazed at how well the lenses clear up by refinishing the outer surfaces.

I wouldn't try to get them open. Trust me, they were never meant to come apart. Almost for certain you would break them getting them apart, and has been said, the discoloration and haze is on the outside, not the inside.

You don't want to open them up. To open them you have to heat them in the oven till the glue melts, not something you do unless you have to.
