What is matrix led?
Matrix LED is an advanced automotive lighting technology featuring individually controllable LED segments that dynamically adjust the light pattern for optimal road illumination while avoiding glare for other drivers. This system enhances safety and driving comfort by automatically adapting to traffic conditions and allowing continuous high beams without dazzling other vehicles.
The high beam is “cut out” for the vehicle in front:
Why should you retrofit
For me the old automatic high beams were the biggest downside of the model 3s built before 2021. Even compared to other older cars the system is almost unusable, because it takes the car insanely long 3 seconds to switch from low to high beams, if an oncoming car was detected. That’s why I retrofitted matrix lights on my 2020 Tesla Model 3 (SOP5).
Requirements
You will need to following parts:
- 1x 1514952-00-D - Headlights for Tesla Model 3 / Y left (Global)
- 1x 1514953-00-D - Headlights for Tesla Model 3 / Y right (Global)
… and tools:
- Diagnostics cable (check which cable you need -> https://service.tesla.com/en-US/diagnostic-cables
- Tesla toolbox for 1 hour -> https://service.tesla.com/en-US/diagnostic-software
- Ratchet with 10 mm socket wrench
- Ratchet extension
- Medium-sized flathead screwdriver (for opening clips)
The upgrade is fairly simple and can be performed in 4 hours with no prior experience. It seems like any Model 3 / Y 2019+ can be retrofitted. Tesla does not perform official retrofits.
Tesla Toolbox Tips

Installation
Follow “Headlamps (SAE-to-Global) - Headlamp Assembly - Pair (Retrofit)” manual from Tesla
Since newer versions the software change can now be made in the cars service+ menu.
You can test the headlights now by starting the light show. It should now be able to project “TESLA” at some point during the show.
Adjust headlight leveling with this “Headlights - Adjust - Global (Wall Method)” manual from Tesla
