I do feel that the lights come on way to early, when it's still bright outside. I don't want to disable it, as I like the auto light feature. The sensor has a brown tinted cover over it. Is that correct? If so, I would like to drill a tiny hole in it to allow more light in. What do you think? Is that a plastic cover that I see, or is the the whole sensor unit. So therefore, drilling it may not be a good idea.
