Xenon emits a blue glow when excited by an electrical discharge for this reason it is used for various specialized light sources such as; photographic flash lamps, sunbed lamps, stroboscopic lamps, bactericidal lamps, high-intensive arc-lamps and hig-pressure arc-lamps. In nuclear energy, xenon is used in bubble chambers, probes and other applications. Xenon headlights and fog lights are used because they are said to illuminate better than conventional lights. Xenon lamps are also used in ruby lasers. Xenon ion propulsion systems are used by several satellites to keep them in orbit. Xenon difluoride is used to etch silicon  microprocessors and in the manufacture of 5-fluorouacil, a drug used to treat certain types of cancer.

“krypton yellow appeared very faint, the green almost absent. Several red lines, three brilliant and equidistant, and several blue lines were seen. Is this pure krypton, at a pressure which does not bring out the yellow and green, or a new gas? Probably the latter!”
