what i've seen, it's either a heatsink at 5w or below or both heatsink/fan for above 10w. i'm gonna fabbing 3-3w parallel arrays for the 3rd brake light and will be using a bar of aluminum for the mount/heatsink. the better the heat distribution the longer they will last.
mia is using "adaptive LED headlights", meaning,

With adaptive headlights, the lights turn their beams around each bend in the road, giving a better view of what's ahead.
Adaptives react to steering, speed, elevation and automatically adjust to illuminate the road. When turning right, they angle right. Turn left, they angle left, reducing glare.
Adaptives use electronic sensors to detect car speed, how far the driver has turned the steering wheel, and yaw. They direct motors in the headlight to turn them, typically up to 15 degrees from center, giving 30-degrees of movement.
If 15 degrees isn't enough, as in low-speed turning in a parking lot or sharp curves, additional lighting can supplement. Some BMWs are equipped with cornering lights. If the car has fogs, small reflectors swivel to direct the fogs off to the side. In the absence of fogs, additional side-directed lamp is installed with the headlights. When moving slower than 25 mph and turning, the cornering lights illuminate up to 80 degrees of additional area to the side of the car. When speeding up or finishes turning, lights automatically turn off.
Sensors prevent the lights from turning when not needed. If not moving or in reverse, they won't activate, keeping them from blinding other drivers.
