Versatile: Building a custom set of headlights, and worried about moisture problems? These bolt-on breather vents are the perfect solution to let moisture exhale from your housings, without letting moisture in.
Simple To Use: Drill a 12mm hole in your housings, insert the front-side of the breather vent in, tighten on the lock nut - and you're ready to roll!
Better: Than the traditional moisture membranes, because they bolt-on rather than just stick on. Therefore, these headlight moisture vents won't ever fall off - and leave you with a big hole in the back of your housing.
Pros: These are the new standard in the most professional way to keep your headlights dry. For the price, the piece of mind is priceless!

The original headlight housings never had a vent to begin with and sealing it up led to condensation issues; this is no longer the case with these installed! Solved the problem on the cheap too.
These are very nicely made vents, a great solution to condensation. They are gasketed and contain a permeable membrane just like oem vents. Many times people think that completely sealing headlights is what they need to do, but in many cases the lights need to "breathe" and to allow interior moisture levels and temp to match exterior levels and temps. These worked very well to eliminate a light haze/condensation issue in my Mercedes headlights. Note that these are not a fix if the headlight is cracked or has a bad seal - these help to replace the function of dirty or clogged oem vents.
