Updated October 2026: BMW Anti-Dazzle and adaptive high-beam features vary by model, equipment, build date and market. A US-spec BMW is not automatically compatible or incompatible based only on its chassis family or a headlight label. Check the individual vehicle before considering coding.
Why can BMW high-beam functions differ on US-market cars?
BMW lighting equipment and available high-beam functions vary across vehicles and markets. A vehicle’s original build configuration, model year, installed lighting hardware and software are relevant. This page does not claim that every US BMW has Anti-Dazzle hardware or that every such feature was disabled for the same reason.
What did NHTSA’s 2022 adaptive-driving-beam rule change?
NHTSA’s 2022 rule amended Federal Motor Vehicle Safety Standard No. 108 to allow manufacturers to certify adaptive driving beam systems on new vehicles that meet the standard. The rule does not certify an aftermarket coding change on a specific BMW, determine that a particular vehicle is eligible, or establish legality in every state.
Read NHTSA’s rule announcement and final rule. For general feature information, see the BMW Anti-Dazzle and NGHB guide.
How can I check a US BMW’s Anti-Dazzle fitment?
- Confirm the vehicle’s model, production date and US-market build information.
- Identify the installed headlight equipment and related vehicle configuration from reliable build information; do not infer eligibility from a model family or a single option-code label.
- Ask for a VIN-specific fitment review before selecting a service option.
- Check applicable current state and federal requirements for the vehicle and any planned change.
The current M-TRI Anti-Dazzle product page lists purchase options and requests the VIN after purchase. If you are unsure which option fits your car, contact M-TRI before ordering.
Does the 2022 rule make coding legal in all 50 states?
No. NHTSA’s rule concerns manufacturer certification of adaptive-beam systems on new vehicles; it does not provide a state-by-state approval for aftermarket coding. Do not treat this page as a legal determination. Check the current requirements for your state and exact vehicle with an appropriate authority or qualified compliance professional.
What method, equipment and timing does M-TRI use?
Those details have not been established as one method for every vehicle and service option. Confirm the process, required equipment, timing and applicable terms with M-TRI for the specific VIN before ordering. This page does not promise an ENET cable, a particular software tool or a fixed session length.
Frequently asked questions
Does every US BMW with adaptive LED or laser headlights have Anti-Dazzle hardware?
This page does not make that universal claim. Hardware and feature availability depend on the exact vehicle configuration, build date and market. Check the VIN and build information.
Does NHTSA’s 2022 rule approve aftermarket BMW coding in every state?
No. The rule amended FMVSS No. 108 for manufacturer certification of adaptive-beam systems on new vehicles. It does not approve a specific aftermarket coding change or resolve all state requirements.
Can I use SA552 or 5AZ alone to choose the service?
No single option-code label confirms the complete vehicle configuration or coding eligibility. Ask for an individual fitment check using the VIN and build details.
Does every US Anti-Dazzle coding session use ENET and take 15 minutes?
No universal method or duration is established here. Confirm service method, equipment and timing for the exact vehicle and offer.
