"Driving lights" or "auxiliary low beams," maybe. Often the goal of factory lights like that is to fill in that dark hole the standard DOT pattern leaves just in front of the bumper.
And why would you need to do that? Lose a set of contacts there? Anything _that_ close couldn't be avoided anyway, so having light there pulling your eye away from the avoidable threat zone is stupid. That's why you're only supposed to turn them on in fog! You are going much slower so that area now _is_ the avoidable threat zone. Such is the theory, anyway. Probably right up there with clean political campaigns and the theory that one should carefully look at where one is merging onto a freeway to make sure there is actually a place to go. -- Jim
