The ability to precisely control the speed and intensity of flashing is a major advantage for many applications. This precise control is especially beneficial in situations where specific signals need to be communicated quickly and accurately. For example, emergency vehicles like fire trucks often use flashing lights to indicate their presence and urgency. With precise control over the rate of flash, drivers can easily recognize these signals on busy roads and highways which allows them to take appropriate action. Additionally, this precise control helps ensure that warning systems are as effective as possible while also avoiding distractions or annoyance from frequent or excessive flashes.
