Rivian’s Heated Headlights Might Be A Winter Driving Recreation-Changer


  • Rivian has utilized for a patent to warmth the headlight lens to make winter driving safer.
  • The patent drawings present a resistive outer ingredient utilizing carbon nanotubes to warmth the lens.
  • There are at present no manufacturing automobiles with heated headlight lenses.

Each winter, Rivian homeowners take to the boards and Reddit to complain about ice buildup on their vehicles’ headlights that drastically reduces effectiveness. LEDs don’t emit sufficient warmth to soften snow and ice, so it stays on the lens till you scrape it off. In some circumstances you must do that each few miles. Rivian has an answer for that drawback, although: heated headlight lenses.

Rivian filed a patent for heated headlight lenses in June 2023. The patent was made public in December final 12 months. The doc reveals that Rivian is contemplating including a heating ingredient that sends warmth throughout your entire lens due to embedded carbon nanotubes. This resolution was chosen in order to not hinder mild going via the lens. Conventional digital defrosters—just like the one you in all probability have in your rear window—layer heating parts in opaque strains, barely lowering visibility.

You should buy aftermarket headlights with a heating operate, however they’re often spherical, making them arduous to combine with most trendy, angular housings. We don’t think about Rivian homeowners could be prepared to combine an extra set of headlights, although, and so they need those on the truck to stay efficient in all climate circumstances.

Rivian may have solved the issue the old school means by putting in heated nozzles to spray the headlight clear, however the heated lenses appear to be a extra elegant resolution. Utilizing conventional resistive heating parts embedded within the lens could be a extra easy, cheaper resolution, so it will likely be attention-grabbing to see what Rivian truly places into manufacturing.

The issue isn’t restricted to Rivian, although. All new vehicles with LED headlights endure from related points, in addition to fogging on the within of the headlights that doesn’t go away. Halogen or xenon lights run a lot hotter, so if you happen to go away them on lengthy sufficient, they’ll start to soften snow and ice on the outside and remove condensation inside.

LEDs are the go-to alternative for many trendy vehicles as a result of they use significantly much less electrical energy than different sorts of lighting, emit simply as a lot mild and provides producers extra management over the place the sunshine goes and the way it’s dispersed. For electrical automobiles, the massive draw is LEDs’ decrease electrical energy consumption, which doesn’t considerably have an effect on vary.

The patent drawings submitted by Rivian to the U.S. Patent and Trademark Workplace uncovered by Motor Authority present a headlight with the standard Rivian design, so it’s unclear if it’s meant for an R1, R2 or R3. If it places this in a manufacturing automotive, it will likely be the second producer to supply this in a collection mannequin, though opponents will seemingly catch up. We all know no automobiles with factory-fitted heated headlights, however you may get aftermarket Oculus projector headlights with heated lenses for the Jeep Wrangler and Gladiator. Let’s hope they’re out there quickly on one other set of boxy, off-road merchandise.
