Mass produced cars have reached the point that a $0.50 saving per vehicle is worth designing and building for. When you reduce the current draw from something that is always-on (like headlights) you increase the life of the LED, you can reduce the gauge (size) of the wires to the lights, you can reduce the size of the alternator, you can load the alternator less, which means increase the service life of the alternator belt and idlers, and (in theory, at least) decrease fuel consumption.
All of these are tiny, tiny efficiencies, but they do add up.
While it might seem penny-wise and pound-foolish, imagine following this same logic for all systems in a modern vehicle. This is why even such a "rugged offroad" vehicle as a Jeep Wrangler has a plastic clutch slave cylinder (weight and cost savings) and why the headlights will dim in virtually all vehicles if you turn on every single electrical device that draws current (the wires are not sufficient gauge for everything to draw max current at the same time).
They're saving actual money on every vehicle built, which is what they care about.
