Stack light in automated production for in-line quality inspection. Stack lights (also known as signal tower lights, indicator lights, andon lights, warning lights, industrial signal lights, or tower lights) are commonly used on equipment in industrial manufacturing and process control environments to provide visual and audible indicators of a machine's status to machine operators, technicians ...
In bi-directional data transfer buses, two opposing unidirectional strobes can be sent from each device. Often the strobe is free running in this case. That is, the strobe continues to toggle whether there is data being transferred or not. Another variation is the sharing of the same bus to transfer the strobe.
Strobes for studio lighting often have a range of power settings. For a given strobe, higher light output corresponds to a longer flash duration. For example, the Flashpoint Rapid 1200 HSS Monolight [1] has a flash duration as long as 5.6 ms (1/180 sec) at its highest output setting, or as short as 68 μs (1/14,814 sec) at its lowest output ...
This reduction in persistence is what reduces motion blur. Different manufacturers use many names for their strobed backlight technologies for reducing motion blur on sample-and-hold LCDs. Philips created Aptura, also known as ClearLCD, to strobe the backlight in order to reduce the sample time and thus the retinal blurring due to sample-and-hold.

Flashing lamp strobes have also been adapted as a lighting effect for discotheques and night clubs where they give the impression of dancing in slow motion. The strobe rate of these devices is typically not very precise or very fast, because entertainment applications do not usually require a high degree of performance.
The horn and strobe on the 7001 and 7002 models are wired in series, causing the horn to produce a distinctive "skipping" sound when the strobe flashes, similar to the "March Time" code. In late 1984, Wheelock redesigned the horn's grilles, making them vandal resistant; and shortly thereafter, pigtail leads were discontinued.
For example, in UK practice, if a white "feather" indicator fails, the low speed feather combined with a green light, which is low speed, becomes a green light on its own, which is high speed. A lamp proving relay would detect the reduction in current when more than two lamps are not working in a failed feather indicator, and prevent the green ...
