Sorry, I disagree. I did a installation with these on another members car & while ill agree the difference in light output is dramatic they were NOT waterproof.
I found the fitment of the toothed ring to the housing somewhat loose which would likely allow moisture to get into the housing (lens) and as was mentioned above I ended up modifying the rubber sealing boots that came off the H4's they were replacing, to try and improve that situation.
It could be that there are variances in manufacturing of the various 7" H4 lenses out there but that collar should be standard.
I think it worked but it wasn't optimal due to the heat sink.
As an aside I posted a review on the item in the 914rubber site detailing the installation but notice it still inst displayed.
