Thanks very much for these photos and video. Obviously different camera settings will produce different white balance and color saturation in photos, but I think I’m satisfied that this run of Daylights are pretty much the same in terms of the colors Lionel has used fairly recently, as in 2013 and later.
The front marker lights issue is a real bore, however, as the ability to change colors was a highly touted feature of these engines. If or when you get it sorted out please post the fix. Frankly I am really apprehensive about finding issues with mine when it arrives!
