If you’ve driven a European BMW and noticed that the high beams automatically dim when approaching other cars — then driven your US-spec BMW and found that feature missing — you’ve discovered one of BMW’s most frustrating US market omissions. This guide explains exactly why it’s disabled, why enabling it is legal, and how to do it remotely.
Why BMW Disables Anti-Dazzle in the USA
BMW’s official position is that FMVSS-108 (Federal Motor Vehicle Safety Standard No. 108 — the US headlight law) prohibits the automatic high-beam dimming behavior. This was true for older implementations — early adaptive headlights had patterns that technically violated the standard.
However, FMVSS-108 has been updated and the current Anti-Dazzle systems in F-Series and G-Series BMWs do not violate the standard. BMW dealers in many states have been enabling Anti-Dazzle as a factory-ordered option since 2022. The hardware has been present in US-spec BMWs for years — it’s a pure software switch.
Is Enabling Anti-Dazzle Legal in the USA?
Yes — in all 50 states.
- FMVSS-108 Section S10.17 permits headlamp systems that automatically modulate between high and low beam in response to traffic
- The National Highway Traffic Safety Administration (NHTSA) has approved automatic high-beam systems since 2014
- BMW itself enables Anti-Dazzle on new US-spec G-Series orders when specified as an option (Select Package / Driving Assistance Professional)
- No state bans automatic high-beam assist systems — most states only require that your headlights not glare oncoming drivers, which is exactly what Anti-Dazzle prevents
Which US BMW Models Support Anti-Dazzle?
Anti-Dazzle requires adaptive LED or laser headlights — it cannot be coded on halogen or standard LED headlights. Check your headlight type (visible on the headlight housing or in your vehicle specification sheet).

|---|---|---|
| G20/G21 3 Series | ✅ Yes | Adaptive LED or Laser |
| G30/G31 5 Series | ✅ Yes | Adaptive LED or Laser |
| G05 X5 | ✅ Yes | Adaptive LED or Laser |
| G07 X7 | ✅ Yes | Laser (standard) |
