Hi all,
I drive a 2005 RX8. For the past few months I have noticed that my rear left light accumulates dense fog. It looks very odd, not to mention some difficulty arises for cars pulling up from behind.
Why does it create fog?
Please suggest ways to get rid of it permanently.
Please find a photo attached for reference.
It has become unsealed and humidity inside condenses on the glass. It's pretty common unfortunately. The fix is to drill a small hole in the bottom of the light, through the black plastic, rather than the glass, to let it ventilate. You can search for more details on where exactly to drill
The more complex but permanent fix is to disassemble the light entirely and reassemble with new seals. This will require baking it in an oven.
The improper fix is to drill it, the correct way is to get the upgraded seal or make your own with marine grade silicon.
Not trying to bash Loki just don't want the OP coming back in a month with a new spiders in my tail lights thread.
I drilled mine. You just take the light out and drill super tiny holes at the bottom and top where the water can drain / evaporate out. Yes, I agree was improper but ended up doing it before I knew about the new seals. That being said, I have minimal problems with the light fogging at least. It does work though and the holes aren't super noticeable and no bugs have yet to sneak inside.

There is a large square hole under the long Plastic clip that clips onto the trunk. I plugged that hole with silicone (after drying with a hairdryer)and have had no fog since. Those gaskets aren’t exactly water proof and there seems to be an opening slit at the bottom of the clear part for water to get out. Once it gets into the black plastic area you get fog.
Just my experience, not necessarily fact.

Thank you mate. Do you have any photos to illustrate?
