And that's exactly why I bought one. I can barely see that thing in the day time unless I'm looking directly at it....which is very rare. When it does blink when I'm looking at the road, I wonder if that is what I really saw. I don't want to have to pay attention to the little faint check engine light when I'm driving hard.
