I bought this light to use on test n tune track days. It was to hard to watch the tach, shift and drive at the same time, so i needed a light that i could mount infront of my eye line that would be bright enough to be seen on sunny days. It is definitely bright enough to be seen in the daytime but its not too bright in the evening at the track. It fits right in with the rest of the car and looks factory. Easy setup, looks great, works just as it says. Money well spent!
