Summary: 


	I saw an article in some cycle mag. (name unknown) a few years
ago about these flashing units. These flasher slowly
oscillate your high beam from full bightness to lower level,
never off. Most units have a (daylight) brightness
meter, so the brighter the day, the larger the amplitude to
the oscillation. At night the unit would be off.
	The article said that in their tests at intersections,
drivers could not avoid noticing the cycles with the pulsing head light.
	In many states (and provinces in Canada) these units are illegal,
because headlight laws say that a headlights must have a constant brightness.
