Now before I ask this stupid question (trust me, it is stupid and I can't believe I am asking it), let me say that I have owned my Grand Prix for 6 years, and never really paid attention to what I am about to ask.
So last week, I was sitting at a stop light, and some random guy got out of his car and came and knocked on my window to tell me my brake lights were out. When I got home, it was night, so obviously my tail lights were on as well.... I had someone tap the brakes, and the top brake light came on, but the two tail lights just stayed illuminated the same, and did not brighten up, like I have seen on other cars.
So, now my stupid question is this..... Are our tail lights supposed to get brighter when you hit the brakes as well? Or is it just supposed to be the top brake light?
