Regarding Heinz query on cooling, undoubtedly the open back bowls would seem to offer better cooling but not a justifiable option for my car. I convinced myself given headlamp location and loose fit of headlamp rim to lens, there will be plenty of air flowing around the standard bowl. After a one hour journey in the dark I could detect no heat at all eminating from them.
I have read that the heat develops also or even more at the back of a LED housing. Perhaps you could feel if there is any heat outside at the top back of the headlight bowl on the wing of the Mog. But I‘m confident that there ist enough space and air.
