The timing light works because it fires the light from the juice to the plug, rather than from juice going through the points. One of the great secrets of old ignitions is that they don't make the spark when the points are closed, they make the spark when the points open, causing the electro-magnetic field that was building up in the coil (while the points were closed) to collapse and discharge the voltage for the spark.
In the old days, timing lights used to come with a little springy thingy, would remind you of a short piece of one of those simple coiled screen-door springs, only smaller in diameter and actually different sizes at the two ends. The bigger end fit over the terminal on your plug, and the smaller end into the terminal on your plug wire, and you clamped onto the springy thingy with the cable from your light that would trigger the bulb to fire. These newer fangled ones use the clip that just wraps around the plug wire to sense the current and trigger the bulb. I don't think they work as well on the old-style wires -- they won't fire off time, but they don't seem to fire as reliably as the old direct connections.
