If a medium white strobe is used on a structure greater than 500 feet (150 meters), the structure must be painted. The common medium white strobe flashes 40 times per minute, at an intensity of 20,000 candelas for daytime/twilight, and 2,000 candelas at nighttime. A high-intensity white strobe is used on structures that are taller than 700 feet ...
The most universal type of light is the headlight, which is included on the front of locomotives, and frequently on the rear as well. [2] Other types of lights include classification lights, which indicate train direction and status, and ditch lights, which are a pair of lights positioned towards the bottom of a train to illuminate the tracks.
Strobe lights are flashing white lights on the furthest left, right and, on larger aircraft and some smaller ones, back points of an aircraft. They are the brightest lights on the aircraft, and are used to signal that an aircraft is entering or approaching an active runway, or for visibility in dark, clear sky.

A hide-away strobe light fitted into a headlamp. The strobe light is the coiled glass tube in the bottom of the headlight assembly, near the center of the highlighted region of the picture (click picture to enlarge).

Neon lamps or light-emitting diodes are commonly used for low-intensity strobe applications. Neon lamps were more common before the development of solid-state electronics, but are being replaced by LEDs in most low-intensity strobe applications. Xenon flash lamps are used for medium- and high-intensity strobe applications. Sufficiently rapid or ...
