Rivian has patented a design for headlights that incorporate carbon nanotubes and heating elements to melt snow, ice, or moisture buildup. This innovation addresses the issue of reduced visibility caused by accumulated elements on LED headlights, which don't generate as much heat as traditional HID or halogen lights.
as HID or halogen lights. That means they're more likely to accumulate a coating of snow, ice, or moisture that can disrupt illumination. Rivian appears to be working on a solution.
In a patent application filed with the United States Patent and Trademark Office , Rivian lays out a design for. That document was filed by Rivian on Jun. 21, 2023, but only published by the USPTO on Dec. 26, 2024.—so named because it's compromised of tube-shaped lattices of carbon atoms less than a nanometer in diameter—added to the outer lens of a headlight. Carbon nanotubes are known to have good thermal conductivity, which might be the reason behind Rivian's choice of this material.
which in turn heats up the carbon nanotube layer and melts any snow, ice, or other moisture sticking to the headlight.Many patented ideas fail to reach production, but Rivian might not have to deal with the regulatory hurdles that previously blocked the latest headlight tech in the U.S. The NHTSA in 2022 finally approved the use of
after nearly a decade of petitioning from automaker. It's unclear how the safety regulator will react to Rivian's integral heating elements, but this does at least show a willingness to revisit archaic lighting regulations.
