I noticed that from mine as well, the thing is that mine has dimmed before. I am not sure if it is faulty or if it takes a certain amount of light to activate. I figured it only worked if someone was sitting in the seat, tested and it worked but then......it stopped working. Not too sure but its a roll of the dice with mine. I am getting a tint soon anyways so I am over it.
