Updated October 2026: This guide now separates BMW’s published descriptions of high-beam assistance from vehicle-specific retrofit eligibility. BMW lighting equipment, names and operation vary by model, production date and market. A chassis family or option-code label alone cannot confirm that a particular BMW is eligible for coding.
What does BMW Anti-Dazzle or glare-free high beam mean?
“Anti-Dazzle” and “glare-free high beam” are commonly used to describe lighting functions that adapt high-beam distribution around other road users. BMW uses terms including Automatic High Beam Assistant and BMW Selective Beam in its own materials. BMW describes some systems as switching high beams on and off, while other configurations can adjust parts of the light distribution around traffic. The exact function depends on the vehicle’s equipment and market.
For example, BMW’s current US driver-assistance FAQ says the Automatic High Beam Assistant can switch the high beams or turn off areas around vehicles ahead and oncoming traffic. BMW UK equipment documents describe Selective Beam as a feature that varies high- and low-beam distribution around other vehicles for specified equipment combinations. These sources describe BMW factory systems; they do not establish compatibility with aftermarket coding on another vehicle.
Does this feature fit my BMW?
There is no single F-Series, G-Series or headlight-option rule that confirms coding eligibility for every BMW. Model, production date, market, fitted headlight equipment, control units and software can affect the available function. A general list of chassis or an option code copied from a different market is not a substitute for checking the individual vehicle.
Use the vehicle’s VIN and build information to ask about fitment before selecting a service. The current BMW Anti-Dazzle coding product page lists its available Vehicle Type options and asks for a 17-digit VIN after purchase. If you are unsure which option applies, contact M-TRI using the details on that page before ordering.
Do option codes such as 552 or 5AZ prove compatibility?
No single option-code label proves that a BMW is eligible for a particular retrofit. BMW’s equipment descriptions are tied to specific model, market and package combinations. For example, BMW UK’s equipment list describes option 552 as Adaptive LED headlights and 5AZ as Laserlights for the listed vehicle range, with BMW Selective Beam availability dependent on other equipment. That document should not be treated as a universal fitment chart for all BMWs or for aftermarket coding.
Check the complete build information and vehicle configuration. If the headlight system or required supporting equipment cannot be confirmed, do not assume coding will add hardware that is not fitted.
How does BMW describe the high-beam function?
BMW’s driver-assistance information explains that the vehicle can use a camera to identify other road users and adapt high-beam operation. Depending on the system, the assistant may switch the beam on or off, or adjust portions of the light distribution. The owner’s manual and BMW Driver’s Guide for the exact vehicle are the right sources for its controls and operating limits.
This general description is not a promise that coding will prevent every instance of glare, work in every weather condition, change a specific iDrive menu, or produce a particular road-lighting result.
What does the 2022 US adaptive-driving-beam rule establish?
NHTSA’s 2022 rule changed Federal Motor Vehicle Safety Standard No. 108 so manufacturers could certify adaptive driving beam headlighting systems on new vehicles that meet the rule. That rule does not by itself certify a specific BMW retrofit or establish that aftermarket coding is legal in every US state. The vehicle configuration and applicable current rules still need to be considered.
For US-specific background, see BMW Anti-Dazzle in the USA: fitment and legal questions. This article is general information, not a determination of legal status for an individual vehicle or jurisdiction.
How do I ask about an Anti-Dazzle coding service?
- Identify the BMW model, production year and country-market specification.
- Check the vehicle’s build sheet or equipment record, but do not treat one code as final fitment approval.
- Send the 17-digit VIN and ask which current product option, if any, matches the vehicle.
- Review the selected product option, current price and applicable service details before ordering.
The Anti-Dazzle product page is the source for current purchase options. Availability, method, equipment requirements, timing and terms must be confirmed for the specific service; this guide does not promise a coding method or session duration.
Frequently asked questions
What does BMW Anti-Dazzle mean?
It is a common term for glare-control or adaptive high-beam functions. BMW’s own names and the way the lights operate depend on the vehicle’s fitted equipment and market.
Can I tell compatibility from F/G Series or an option code?
No. Chassis family and option-code labels do not confirm retrofit eligibility by themselves. Check the specific vehicle’s build information and ask M-TRI to confirm fitment by VIN.
Does the 2022 NHTSA rule make BMW Anti-Dazzle coding legal everywhere in the United States?
No. The rule allowed manufacturers to certify compliant adaptive-beam systems on new vehicles; it does not establish the legality of a particular aftermarket coding change in every jurisdiction.
How long does Anti-Dazzle coding take, and what equipment is required?
This guide does not state a universal method, equipment list or duration. Those details can vary by service and vehicle; confirm them with M-TRI for the specific VIN and product option.
