I have mositure in left side HID low beam and high beam headlights on a '99 GS4. I've inspected the lights closely and there are no cracks in the lenses and all the rear access covers are in place and have good gaskets.

Questions:
Is there a typical place for moisture to enter these lights?
Best way to remove the moisture?
Assuming no collision damage are the headlight units covered under 4yr/50K warranty?

 

It's normal to get a little moister in the headlights if you wash the car, or when it rains, there should be a small hole or tube in the headlight somewhere just for excess moisture to drip out of, When I first got my GS, I washed it and it got moisture in it one time, but hasn't had it since

GJS, unfortunately, Lexus seems to have an across-the-board problem with headlight seals. Virtually every model has complaints along these lines. My SC had (at different times) both headlights replaced for moisture within the housing. Your dealer ought to be willing to replace under warranty.

BTW, hate to contradict ShowGS, but there are no drain holes in headlight assemblies. These are (theoretically) sealed boxes.

Here's a link that talks about cleaning lenses, but since you have to disassemble/reassemble the unit, it explains resealing the plexiglass........

 

LoL yea I kinda figured that since it was what the Dealership told me... Because when the light filled with a little moisture one time, I told them about it when I was at my 1000 Mile checkup, and the service guy told me that it'll happen once in a while , but it hasn't happened again, if it does... By changing the headlight that should fix it right?
