The JX has auto light, if left on auto, will turn on when it is dark and off when it is bright, when driving. Mine never turn off. It will turn off automatically after a few seconds when the engine is off, but when I am driving, it will never turn off, no matter how bright it is. I set the sensitivity to low, suppose to turn on very late when it is getting dark. But it is always on when I set it to auto. I'm in US so there is no DRL. Does this happened to any one?
