SC400 Headlight issues (condensation) - I can't fix this ...

I reused the rubber boot from the old projector, but there is still a gap around the plug. the other day I went for a car wash and I got some intense condensation in the passenger headlight most likely from improper seal, cause while I was doing the retro things wouldnt fit right so I had to repeatedly reheat and pry apart. so I think im going to rip them apart one last time and use the silica packs, then reseal them properly by removing the old gunk and then use silicone. If it still fogs im gonna get a pipe end cap and drill a hole through the back for the wire then seal that around the back of the projector. gonna do this probably in the next few weeks so i'll let you know. unless you solve the problem before me, then you should let me know.

there still looks like theres a gap around the connector and boot, that's basically how mine looks at the moment. I think after I reseal the clear lense to the housing things will be fine. my driver side is holding strong. I only took that side apart once and the job was done. sucks for you to have to deal with the constant rain.

same thing with me, everyone was actually looking forward to my baking skills with the headlight every weekend to fight condensation. it's been 3 weeks now since i drilled all the small holes in the black housing and it has been raining off and on for 2 weeks...PROBLEM SOLVED, crystal clear all the time, even after raining or a car wash.

I just wanted to thank everyone for chiming in ... especially those who recommended that I search for threads on the subject. I spent weeks searching ... that's why I tried OLT's headlight "baking" technique.
I just wanted to say that I SOLVED the problem ... no more condensation.
The solution? I followed some advice within this thread (and others) to try silica packets. I inserted a number of them between the black headlight case and reflector and the condensation disappeared within two days ... and has not reappeared since.
Thanks for the advice about the silica gel packs ...

What worries me about drilling holes in the bottom of the headlight is that its more open to dust from driving and mist getting in when it rains because I removed the intake snorkel and installed an aftermaket cone, so now there is a direct path from the vent beside my foglight to the underside of the headlight and intake.

I've done the retrofit on my headlights and have not had condensation problems. I would definitely advise against drilling holes in the housing as that may allow it to vent but will also let more dust and debris get in. I didn't even use the silica packets. I just made sure to use a liberal amount of black hi-temp silicone all around the lense before I sealed, and another bead of silicone around the lense after squeezing the lense against the housing. Took it to a high pressure carwash to test it out after it cured and no leaks.
After doing headlight modifications as a side job for over 25 S2000s, an Accord, a WRX, and lastly my own Lexus, none of them have had condensation problems.
So put those drills away and toss the silica gel packets, a properly sealed headlight doesn't need any of those things.

do you happen to have pics of what the back of the headlight look like? i'm about to seal the gap behind the projectors but i'm just wondering if it'll be a PITA to remove the bulb just in case it goes out

What is that rectangle piece on the headlight? I've never seen that before.
RE: Condensation, I'd advise against drilling holes in the housings. I'd replace the vent tube filters with some new foam and use silica gel packs to minimise condensation.

rectangle? you mean the glass? if so, that's where they kept the water thing for beam adjustment
a question, if i ignore the condensation, will it do damage to the electrical stuff?
