Hi everyone,
I found it a bit annoying that when you flash your headlights when xenons are on that the shutter opens AND the halogens come on.
I tried to code this out but found that the halogens would completely disable, even when the xenons are off, they act as flash to pass. Didn't think this was safe for the ballast as you're not letting the bulb to light fully.
I found a way how to get Halogens as flash to pass when lights are off and when only sidelight is on, and ONLY the shutters open when flashing to pass when the xenons are on.
NOTE: it has to be OEM xenons and you need the shutter wires run from pin 11 from the headlights to the CECM
Hope the video below will help anyone who wants to do this.
