Let's think about a headlight assembly.
Without a board: you need a big power wire for low beams, a big power wire for high beams, a smaller power wire for turn signal. And that's all you can do.
With a board: you need a big power wire for everything. And a two tiny wires for CAN--so you're already ahead. If your beams can move, or be directed, or have LEDs that can be modulated, or have a washer, you start coming out WAY ahead.
