The build up you saw only appears when i go thru car washes as the pressure builds and goes into headlights. In winter it barely to never builds up. I can't speak for the Philips as as the brand i use has a unit that prevents ice and snow from getting it and there is heat. From my personal useage on multiple generations of crv switching to this i recommend if you could theCan you please comment on how these LED bulbs behave in the winter with more humidity, snow and water around? I am about to buy a set for my EX-L from Philips (ultinon 9000 pro) and curious to hear feedback on the heat (or lack of for LEDs) and more moisture in the housing and issues with snow/ice on the front side of lamp.

Hope that help!
