    How does it operate ?

    The modulator automatically controls the depth of modulation between 5% & 70% depending on ambient light level. On a very bright day, the unit will operate at 70% depth (Maximum effect). On a dull day, or as daylight begins to fall towards dusk, modulation depth will gradually reduce to 5%, then, in accordance with US DOT regulations, modulation will cease at dusk.
