I've had a similar idea to the brakes, but in my version the intensity of light was linked to the intensity of the braking. That way if you're just cutting a few mph off your speed, it doesn't really matter and the light is pretty dim. If you're braking moderately, the light comes on bright enough to indicate that you're braking, but if you slam on the brakes then the light illuminates strongly and brightly.
