I always have my lights on, regardless of the weather or time of day. I've never actually counted, but it seems like a slight majority of other cars on the road around here do the same. I initially started turning them on because I drove a light gray (read: road-colored) car and I wanted to make myself more visible. I've noticed over the past few years, though, that no matter what the color of the car, having the headlights on makes it more visible (and easier to judge speed) so I drive with my lights on all the time, no matter what I'm driving.
Who else does the same?
