so i washed my car yesterday and it was a bit cold yesterday night , i noticed some fogging inside the lens. today i noticed some condensation still left inside the lens of the passengerside, im hoping it will subside, but is there anything i can do to remove the condensation or at least prevent it in the future?
"Condensation - Moisture inside today's plastic headlight assemblies can collect on the inner surfaces of the lens, compromising the beam pattern, and allowing exposed electrical connections to oxidize (ending up in bulb failure). The problem is usually exacerbated by humid weather, or by driving your car through a car wash. Moisture enters the lights through the vents that allow for expansion and con*traction as the air within the light chamber heats and cools. Most composite lights are designed so that airflow sweeps away the condensation as they warm up, however if the vent tube is clogged or the housing is cracked, the condensation may never go away."
I'f I'm not mistaken our lights work the same way... look around at them.. and take a bottle of air... and blow them dry... and make sure all the vents and what not are clean...
The way the factory works with this is to turn the high beams on... leave it for twenty minutes... and if there is still condinsation in the headlight.. the vents are clogged and need to be cleaned out.
I dont know about sealing them... I'm research this a little more before doing that to tell you the truth.. these assemblies were made to allow hot air to expand and vent out of the assembly... sealing it shut leaves no path for hot air that is generated from the bulb... if you think sealing it up will worth.. then by all means... maybe you are thinking of sealing it up and not sealing the vents... I dont know.. I'd have to look at a head light to tell you...
i sealed mine with clear silicone the two times i've opened them up to replace a broken DDE. They don't fog here, and everything else does in the morning because my baby....doesn't get the garage, vette and lotus come first
