If bright lights are safe, brighter lights are safer—right? Not always. The NHTSA has required Tesla to recall 63,600 Cybertrucks for lights that could potentially blind other drivers.

The recall affects 2024–26 model year Tesla Cybertrucks. The automaker has already written a free over-the-air software update to make the lights safer. But because this is a safety issue, it still needs to notify owners that this latest update is critical and maintain a public list of which Cybertrucks have yet to be updated. This is officially Tesla recall SB-25-00-008.

The lights in question are the Cybertruck’s parking lights. These bright lights’ default settings are to switch on when you unlock the vehicle, open a door, or shift into park, and to turn off after a few minutes of driving. Currently, drivers can set the parking lights to stay on while driving. This option may be why they can’t be brighter than the NHTSA’s maximum for driving lights.

Federal standards for minimum and maximum headlight brightness haven’t changed since 1997. However, the IIHS began considering headlight effectiveness as part of crash ratings in 2016, and many automakers have since swapped to LEDs that are as bright as legally allowed.

In a recent study, the IIHS claimed that increasingly bright headlights aren’t causing an increase in crashes. It did admit that bright headlights can still be a problem for some. “Glare can be disconcerting to some drivers, even at levels that don’t exceed the IIHS tolerances. Moreover, people with age-related macular degeneration and other health conditions can be especially sensitive to bright lights.”
