White lights are meant to universally portray the oncoming side of a vehicle (be it white headlights, or white reverse lights). This seems to add unwarranted confusion to the roadway. What is the problem with red lights in the rear? We are not trying to light up the roadway behind us, are we? I understand the benefits of staying visible on the road at night (and use many lights both red and white myself) but would hesitate going against traditional lighting techniques that are already seared into the brains if the collective motorists.
