Primary venting

Now, this might just be a little too much “rocket science” applied to an old British bike. - I’m not sure I would do it myself, but anyway, this gadget might just do the job. The company I work for produces lighting fixtures both for indoor and outdoor use, and we have had problems with fixtures “sucking” in moisture through cable glands, whenever fixtures cool down and a vacuum occurs, resulting in a light fixture filled with water. By mounting this GORE-TEX “membrane vent” in the housing, air is now allowed to get in and out, but water is blocked out. Works great. Check out these two links and learn more. http://www.gore.com/prevent/ and http://www.gore.com/prevent/Documents/TypePOV-m12x15reva.pdf / Niels
