I'm torn on this build, but most of it is because of the customer specs, not your install.
The front microns are useless. I would've gone with a bigger dual color light with a larger footprint, and gotten them with white. Integrate flashing white into them, R/W and B/W, and then the white could go on takedown as well. Speaking of takedown, I'm not sure why there's a separate takedown and flood. Never understood that. There should be a single takedown that floods every front white light. Then have some modules in the bar with a higher priority so R/B prioritizes on some or most modules when takedown and flashing are both active.
The rear of the car is really busy. I like that you guys separated the colors and slowed it down in park, but there's no amber, and it's just overall really busy. I think I would've cut the rear window lights completely, both the inside ones and the ones on the spoiler. Just leave the license plate lights, the taillamps housing ones, and the Legacy bar of course. This would've cleared up funds for the front microns to be replaced. Alternatively remove every rear light, and add a full interior bar to the rear window that is 100% synced with the Legacy bar up top (Same colors, same patterns), so if both are visible it'd look like one bar. Then just flash the brake lights alternating with the reverse lights like the vics used to do.
The side eclipse lights, I like that they are red and blue, but flashing the whites on then during stage 3 in gear would add effectiveness. I'm a huge fan of flashing white to the front and sides when rolling.
Just my opinions. Nice build overall. I like your flash patterns. Can we see a video with stage 1 and 2? I'd be interested to see what you/they chose for those.
