They're 3 plates tall, 2 plates long, with a lip extending a half plate lengthwise. That means that plates can easily be aligned to the studded side to conform to the 5:2 plate to stud ratio, which is the most important fact to remember when build SNOT. Stack five plates in SNOT and you get a width of two studs. Two of the five plates can be replaced with the 2-long headlight brick, allowing the headlight brick (if placed at the right point in the stack) to attach to studs-up plate and have everything sit flush. And as with all Bricks Modified with Stud(s) on side, the SNOTed bricks will be a half plate above the bottom of the brick, which is the height of all the other studs on the studs-up surface. Since I also attached the headlight bricks so that their tops are at the same height as the now bottom edge of the half-cylinder, the edge of the cylinder will align with a whole number of plates and tiles so it sits flush on all sides. If you had wanted to use the other Bricks Modified with studs on side, then you would extend the 3-plate wide assembly attached to the headlight bricks to 5-plates wide, so that it spans an even two studs and the Bricks Modified can attach to the end without spoiling the ratio.
