Tesla Quietly Rolls Out New 'Dynamic Headlight Leveling' to Select Cars
The unannounced feature, spotted in software version 2026.38, automatically adjusts low-beam aim to reduce glare for oncoming traffic.
Tesla has begun testing an unannounced lighting capability called “Dynamic Headlight Leveling” on a limited number of vehicles. The feature, included in recent software updates such as version 2026.38, automatically adjusts the aim of low-beam headlights to improve visibility and reduce glare for other road users.
What Happened
The rollout is currently restricted to an extremely small fleet across multiple regions, including the United States and the United Arab Emirates. The update appears on both the Model 3 and the Cybertruck, suggesting it is not tied to a specific model or hardware generation. According to the software description, “Low beams will automatically adjust their aim based on driving conditions and nearby traffic to maximize your visibility while reducing glare for other road users.” The system utilizes internal leveling motors to adjust the physical hardware of the low-beam projectors in real time as vehicle pitch changes due to acceleration, climbing, or cargo weight.
Why It Matters
This feature automates a process that traditionally requires manual intervention. While many European vehicles include a rotary dial for headlight leveling, most North American cars lack this physical toggle. Tesla currently offers a manual “Headlight Adjustment Mode” within its Service Mode, requiring drivers to calibrate aim using the touchscreen. Dynamic Headlight Leveling is distinct from Tesla’s existing Adaptive Headlights feature, which uses Matrix LED arrays in high-beam modules to selectively dim pixels. Because the new leveling feature targets low beams, which do not use Matrix LEDs, it represents a different approach to managing nighttime glare. The limited release indicates Tesla is likely in a data-gathering and validation phase before a wider deployment.
The Bottom Line
Tesla is quietly validating Dynamic Headlight Leveling on select Model 3 and Cybertruck vehicles via software version 2026.38. There is no announced timeline for a broader fleet release, but the feature is expected to expand as validation continues.
