Hi.
I just picked up my 2023 718 Cayman T today. I absolutely love love it! However there is a little condensation on the inside of all 4 lights. Front headlights and rear. Why? Will it go away? I plan on contacting the dealer tomorrow. I was wondering if anyone else has experienced this. It has been sitting at the dealer outside in S CA for a few weeks as I’ve been out of town. It has rained pretty hard here. I wonder if that’s the reason for the condensation. Any thoughts would be helpful.
Thanks,
Ron

Perfectly normal. Do a search on the forum and you’ll find it.

sadly it`s normal.

The reason its normal is not because they are all defective leaking crap. The lights are NOT sealed units, therefore condensation happens. It also goes away depending on weather conditions/heat/etc. It was designed this way.

Right. Like many modern headlights, they are vented to mitigate heat buildup. Moisture in the air that enters the headlight will condense under the right conditions.

Condensation is perfectly normal.

Yep I get it more often in the spring and summer (its pretty hit and miss), but as above the dealer tell me its normal and will only investigate if it remains for 24+ hrs.

I think its a pretty poor design to be honest and it must diffuse the light output somewhat as well.

Even though you are right, no other cars did it ever. Or motorbikes. All of them had vented plastic headlights and tail lights.

What kind of bulbs were inside them? Xenon and even more so LEDs, produce less heat than halogen bulbs. So they have less defogging effect.

High wattage LEDs produce quite a bit of heat, but its not at the light diode itself, its in the power supply built into the led unit.

High power LEDs are also generating lots of heat in headlights, not just the power unit. Taillight is more simple (nd more condensation)

Both. Still no condensation.
The worst is the taillight of the 718 also did not have issue with other car`s taillight.

There's a simple fix for this. Lots and lots of silica gel.

Thanks! Good to know.
