As well as the auto leveller, you will need the headlight ecu which sits under the dash and the levelling motors.
Self levelling lights are also known to have faults, so you could do all that and end up with one of your lights periodically pointing at the floor two foot in front of you, or worse still both.
i dont think hondas have headlight ECUs (brains) because there is only a fuse for power to the sensor, the sensor is a brain its self changing a varible resistor into three set resistances witch the level motors read and ajust acordinly lol hope that made sences :huh:
i do no the BMWs, Audi and Mech all have ECU unit for the headlights because they work not only on rear sus but also on angle to earth and speed pulse. some of these even have the "look around coner" or turn lighting built in. smart Germans
