I have owned a 2018 Mazda 3 BN (Canada) for a few weeks now. Since I live in Europe I need to replace the headlights. I am an electronic engineer so I can handle the electrical installation without any problem. I have regular halogen lights even without manual leveling.
I want Full LED lights and here we have 3 types:
I did a little investigation on the lamps, because about the control units has already been written more than once.
So we have the following lamps, I am writing about the EU versions for the M3 BN:
However, I would like the ADB version with the control module B63E-51-027B. Unfortunately, this module cannot be get anywhere. Maybe at an authorized service center, but that would be to expensive.
AFS
I accidentally bought one (7-pin BAAR T version) lamp for experiments, that is with AFS.
I peeled off the lamp shade and there are two electronics and there are two motors: a swivel actuator and a leveling actuator. The electronics appear to be the same as in the 8L lamp (without AFS and without ADB), there is one difference, as there are additionally 3 wires to the swivel actuator.
LED Electronics inside the AFS lamp:
Visible the swivel actuator near to 7-pin connector:
So I need the B63D-51-02X module with AFS. You can sometimes get one for about $150 but even much more.
I looked at the diagrams from the AFS M3 (BN) and MX-5 (2016):

M3 they are similar to AFS MX-5 (2016), practically the same:
MX-5 AFS Module diagram
I wonder if it is possible to use this module from MX-5 (AFS KB8B5102X 2017-2018) in our M3 BN, (usually the equivalents have the 5102X end)? In my opinion, yes, at least from the electronic side. I just don't know what are the signal levels to the lamp actuators, maybe there are some differences here. ALS sensor should work similarly, or maybe exactly the same.
Why MX-5, because these second-hand modules are available and not expensive (like $30-$50). I would like to try to match our M3s.
I wonder if it is not also possible to use modules from CX-3, 6 etc.? What do you think?
ADB
I am still considering if it would be possible to retrofit the version with ADB (without AFS) using other models?
What about the B63E-51-027B module, can it be replaced from other models like CX-5?
I am not sure, but it would be more difficult to replace the 51027B module with others from the CX-5 or CX-3, because the design of the lamps and the number of LED diodes may be different. Or maybe not?
I want Full LED lights and here we have 3 types:
- with AFS (swivel)
- with ALH (ADB - Smart Adaptive Headlights)
- without ALH and without AFS (simple only auto leveling)
I did a little investigation on the lamps, because about the control units has already been written more than once.
So we have the following lamps, I am writing about the EU versions for the M3 BN:
- BAAR (T), BABD, BABH - LED lamps with AFS
- BABE (DM), BAAS - LED lamps with ADB
- BSP5 (8L), BABG - LED lamps without ADB and without AFS
However, I would like the ADB version with the control module B63E-51-027B. Unfortunately, this module cannot be get anywhere. Maybe at an authorized service center, but that would be to expensive.
