Yeah I have the same problem but I don't drive at night so I haven't bothered to fix it yet. From what I have found out, there is a pair of switches located next to the driver side headlight bucket, that you access in the front trunk up by the radiator. Both switches have adjustment pads and both have to be adjusted to turn off and on at the end of their travel. If you look up there you will see what I am talking about. But that may be what is going on, if you can lower the headlights by hand and it acts smoothly, it is one of those two switches that isn't clearing.
