Bolt-On Breather Vent Moisture Breathing Vent for Headlight with Moisture or Condensation (qty 2 included)

Worked perfect for my cheap headlights that I retrofitted projectors into. Its been over a year I believe and I ahve not had any moisture issues whatsoever

I had water in my Driver's headlight and it was a simple fix but I installed these little vents into both headlights. These are simple to install and great to have in place to prevent any build up.

Works great at keeping a water tight enclosure water tight.......they equalize outside air pressure with the inside prevent water from being sucked in though the gaskets when it rains

You get 2 of them not 3 as the picture shows.

Solved my headlight condensation problem great item

Not sure if it’s my set up or the wrong style vent for my application. I have a 11 300C with aftermarket headlights and my passenger side began showing moisture after week 1. Because I already assembled it I decided to roll with it until I figure out a plan. Don’t have time to tear off the headlight and do a reseal, but do have time to put on a vent. I set it up directly to the back of the housing near the main cap for the LED bulb. Pointing towards the car straight no angle. Continue to experience moisture when humid, but it does actually clear up on a hot day. Kind of confusing. But o decided to put it on my driver’s side lens to avoid the same issue in the future and found that it does not build ANY moisture even now. So I believe I will need to do a headlight reseal just was hoping not to. Vent is good to clear light moisture, but will not help larger leaks. Good value for the money.

These vents are absolutely incredible. I bought a set of headlight assemblies one of which was fogging up horribly. I spent close to $400 on them and the manufacturer wasn't willing to do much to help. I installed 3 of these vents on that assembly and after a couple of days it's completely cleared up. Thank You.

I order two pairs of these to alleviate moisture buildup in my BMW active headlight assembly. I am using it only buy time until I replace the headlight, but it has worked so far to keep moisture buildup from occurring. Now I can extend the life of the motors and modules while I finish other projects first.
