Yes, but it came on plenty of times before and we detected no problems (yes, we checked everything). The fact of the matter is, if the brake light comes on whenever it pleases, people will be inclined to ignore it. Therefore I find brake pedal feedback (such as sluggish response) combined with brake light illumination to be a greater indicator than only the brake light illuminating. If we didn't stay vigilant and check our system every time the light came on, we would have ignored the situation and plowed into something (or perhaps someone). ABS is great, yet its feedback lacks.
