All Resources For GORE® Automotive Vents for Rear Lamps and Specialty (CHMSL) Lamps


Safety, performance and styling are all key elements in the design of automotive rear lamps and specialty (CHMSL or side marker) lamps. New designs must incorporate advanced venting solutions to effectively mitigate the damaging effects of environmental factors.

Venting products for rear lamps or specialty CHMSL lamps must reliably withstand rain, sleet, snow, dust, dirt and debris. And they must excel at managing lamp pressure differentials, to prevent water ingress, condensation and ultimately, lamp failures and recalls.

Gore provides proven venting solutions to meet these needs. Our Vents:

  • provide effective moisture diffusion to solve new clear-lens condensation challenges
  • manage pressure differentials and keep environmental contaminants from infiltrating lamp lenses and housings
  • continue to vent regardless of whether the car is moving or parked

For over 20 years, Gore has partnered with global OEMs and Tier-1 lighting suppliers to advance rear lamp and specialty (CHMSL) lamp design and reliability. By relying on our expertise, suppliers are confident in their products’ integrity, no matter what conditions they face.
