In my earlier post I wrote, "...Fog lights have ... a sharp horizontal cutoff on top of the illuminated field (almost the same as the low beam cutoff on Euroheadlights (such as you installed) or e-code (sealed beam substitute) headlights for older cars...."

I should have clarified that the "almost the same" is because the fog light's cutoff is perfectly horizontal, intended to only illuminate the pavement to the edges of the roadway; whereas your Euroheadlights' low-beam cutoff rises to the right (except in the U.K.), so that beyond the edge of the roadway to that side you can see taller objects such as pedestrians and deer (about to jump out into the road in front of you) as well as road signs, and yet not blind oncoming drivers on the left side.

Also, fog lights should NEVER* be aimed as high as the low beams of your Euroheadlights. That is, the fog light's upper horizontal cutoff should (looking from the side) slope downward so that, aiming them against a wall, the farther away the car is from the wall, the lower the cutoff should be. In contrast, the left-hand (lower than the right) horizontal portion of the Euroheadlights should be horizontal -- i.e., at a constant height against a wall, regardless of distance.

* Of course, BMW-owning idiots, and teen-aged japanese car-owners, are notorious for aiming their fog lights upward like high beams, blinding everyone else on the road -- no doubt, you've experienced this yourself. They think it's OK because they're "fog" lights, and they run around with them on all the time.
