They are a little foggy but the color is yellow.  I can turn my brights on and they don't bother oncoming traffic a bit!   Even the driving lights are yellow, brighter than the headlights but still dim.  You may be right, though, which is why I wanted to make sure of the 1999 Navigator headlights for my 03 so I can change them out.  I will probably put LED's in at the same time.  Thanks
