Headlight Condensation IS300H F Sport

Colinb623 · November 26, 2023

Has anyone had this on their 300H ?

My 2016 F Sport has a very slight condensation build up in one of the headlight . Has anyone tips or tricks to solve this ?

Usually after a car wash theres a mist right at the top of the headlight, cant say Iv noticed it being a problem impacting the beam etc.

Look out for the headlamp being cracked unlikely though its usually just condensation getting past the headlight seal. You could try using a hair dryer but it will likely come back be careful you dont melt the clear plastic. My advice would be to leave it alone unless it holding a puddle of water

In principle it should not happen. I would go to the stealership and have the seal changed. So if it happens again, it's on the brand to fix it.

To my knowledge the seal is not usually replaceable its a sealed unit so to speak. If your good at DIY you will need to remove the bumper & get to the headlight unit & use clear silicone sealant to make it water tight but thats in the hope it will resolve it.

Its well out of warranty by now I think you mentioned the car is 2016? Coming upto 8 years wouldnt be a Manufacturer fault as such just wear & tear with age seals become brittle & with a heavy downpour some water maybe finding its way in. The IS300H Headlights are not coded in so you could probably get away with a replacement unit but I bet it would cost a pretty penny.

Try ignoring it if you can help it, until it really stands out then just repair or replace.

Gonna be a waste of time taking it out and trying to seal it.... ive tried and failed....

For all the effort required to take bumper off and remove headlight.... Just get yourself a new one.

See my guide pinned to this forum on how to do it, i even have photo comparing the old headlight with the new one.

One thing, I used to do was, Placing silica gel packets inside the headlight housing which can help absorb excess moisture. Make sure the gel packets are secured in a way that they won't interfere with the light components.
