Dectane Depo LED Tail light condensation / fog - I know it has ben cov


Recommended Posts

So I have read every thread regarding the Dectane/ Depo 997.2 style LED taillight replacements for the 997.1. It is apparent that the LED's do not give off enough (or any) heat to keep the moisture / condensation / fog out of the clear section in the middle.I started with leaving the unit sealed...and it fogged a little.....I read about taking off the two clear plastic vent caps and fabric to allow them to breathe....I have done that. I try running with them ON and with them OFF just on when braking etc.....Still get fog. It is about 20 - 30 degrees F here, but sucks to spend that much on lights and have no way to keep them from fogging.Some say when they removed the plugs it cleared up...I have not been so lucky. Only driven a handful of times for short distances though...Maybe it needs more time??So the lights are near the engine compartment, which produces plenty of "free" heat. And I am starting to think like a mad scientist now....Would appreciate thoughts on if I just need to wait a bit with the caps off, or if I should start experimenting? And would appreciate thoughts on if my idea would create any other potential issues (it is not fully baked yet)I am thinking of possibly trying to get some tubing the size of the vent holes on the light and trying to see if I can connect one end to the lights and the other somehow in the engine compartment to have heat "pumped" in, in lieu of incandescent bulbs?? Maybe a dumb idea... I am just trying to think of a way to get some heat in there to dry the moisture!???

These are on my 997 Turbo BTW (and look great...except for the occasional fog :))Thoughts, jokes, ideas, solutions, sympathy, etc...AppreciatedTHANKS!!!PS Also posted on 6Speed & Rennlist

Dectane / Depo come with air vents - they have plastic plugs inside for shipping which should be removed on installation - you can transfer the rubber hoses from OEM to Depo if required. The vents are there to dry out condensation rather than prevent it.

If you want to use the OEM rubber you will need to warm it up to stretch it to fit, The rubber right angle serves as an indirect vent to prevent moisture running in, but as you drive the car air rushes in and clears it anyway. It depends upon your climate whether you feel these are necessary I suppose, or whether you just leave the clear plugs in place.
