Safety, performance and styling are key elements in designing automotive headlamps, fog lamps and rear or specialty (CHMSL) lamps. But any of these elements may be compromised by environmental factors like heating/cooling cycles, humidity, dust, debris, fluids or condensation.
GORE® Adhesive Vents for exterior automotive lighting can protect lamp assemblies from damage, degradation or premature failure in harsh or extreme environments.
They effectively block ingress of rain, sleet, snow, dust, dirt and debris. They respond rapidly to pressure differentials, which can stress seals to failure. Our vents quickly equalize both over-pressures and dangerous under-pressures that could pull water, contaminants and condensation into the housing and onto the sensitive electronics.
NEW GORE® ADHESIVE VENT AVS 100 -
Engineered for the challenges of LED lamps
High-value LED lamp assemblies require superior venting to protect sensitive electronics from water and dirt, and to avert owner complaints of “foggy” or “dirty” headlamps. LED lamps are prone to these problems because they generate heat only at the electronics at the rear, which creates a cold spot at the front of the lens. Any moisture that permeates the housing – even a few drops worth – will condense at this cold spot, clouding the inside of the lens. Such condensation, along with any particulates it carries, will be extremely noticeable through the clear lenses of today’s sophisticated LED headlamps.
GORE Automotive Vents for adhesive installation solve this problem. Their proprietary microporous membrane allows air and gases to pass through freely, so that any moisture is diffused before condensation becomes a problem. Yet the pores of this membrane are 20,000 times smaller than a water droplet, so it blocks entry of liquids, as well as fine dust particulates.
Field-proven, in all regions of the world
Millions of GORE® Adhesive Vents are in use across global automotive platforms, because they:
- Rapidly and continuously equalize pressures in response to environmental changes… whether the vehicle is moving or parked.
- Effectively diffuse moisture vapor to solve lens-condensation challenges.
- Reliably block fine dust, dirt and road debris, as well as water splashes and sprays, from entering the housing.
- Offer a choice of performance options, providing a versatile solution for all lamp types (LED, Xenon, Halogen) and for clear and colored lenses.
- Are engineered to provide a secure and durable bond with most typical plastic and metal housing materials.
For more than 20 years, we’ve partnered with global OEMs and Tier-1 lighting suppliers to advance the reliability of automotive headlamps, fog lamps and rear and specialty lamps. We have technical support and testing centers in the US, Germany, Japan, Korea and China, so our application engineers are easily accessible – and ready to work in close partnership with your design team, from product concept through manufacturing integration.
Gore offers qualified vents for headlamps, fog lamps and rear and specialty (CHMSL) lamp applications. All our vents are extensively tested and evaluated in both laboratory and field conditions, to ensure they will perform consistently and reliably for you.

AML Systems (AML) and W. L. Gore & Associates (Gore) introduce a new technology to actively prevent condensation and put headlamps on a new level of protection. AML’s Condensation Management Device (CMD) enabled by GORE™ Condensation Management Products leverages electrical power and regenerative desiccants to actively remove recurring moisture from automotive headlamps. The new technology will be presented today at the Conference SIA VISION 2018 in Paris.
W. L. Gore & Associates will highlight solutions for reliably protecting automotive components in harsh environments, during the SIA VISION, October 9-10 in Paris, France. The primary focus will be on Gore products for automotive lighting and electronics/driver assistance systems.
Headlamp condensation is a recurring evil for the automotive lighting industry. It will become even more of a challenge as the industry moves to full-LED headlamps, because existing venting solutions can only reduce –not sustainably prevent– such condensation.
W. L. Gore & Associates will highlight solutions for reliably protecting automotive components in harsh environments, during the 16th Driving Vision News (DVN) Workshop, January 30-31 in Munich, Germany.
