'cause I don't and I understand optics pretty well.

ellipsoid \El*lip"soid\, n. [Ellipse + -oid: cf.
A geometric surface, all of whose plane sections are either ellipses or circles

Note: The ellipsoid has three principal plane sections, a, b, and c, each at right angles to the other two, and each dividing the solid into two equal and symmetrical parts. The lines of meeting of these principal sections are the axes, or principal diameters of the ellipsoid. The point where the three planes meet is the center.

or in combination with a parabolic reflector.

this may sound a little stupid, but please tell me the difference between eppsiloid headlights and normal and would my 1990 525 have eppsiloids?
