The voltage drop is simply from the wire resistance, your headlight draws several amperes so part of the battery voltage gets lost as heat in the wiring. To get a better reading, connect the wires closer to the battery, or on a circuit that doesn't draw much current. At the horn, the voltage only drops a bit when you honk. The yellow wire at the horn is 12V, I connected the +12V (red) wire of my tach there.
