'''Chemical light sticks''', also known as '''"chemlights"''', are plastic tubes containing two isolated elements that when combined, are capable of producing light through chemoluminescence.<ref name="CF100">[https://www.halowaypoint.com/en-us/news/sweet-centennial '''Halo Waypoint''' - ''Canon Fodder #100: Sweet Centennial'']</ref> 

==Background==
They are currently used by the [[United Nations Space Command|UNSC]]. When lit, they glow a sickly yellow color, and are used primarily to mark areas or as emergency lighting.<ref name="FS">''[[Halo: First Strike]]'', Chapter 12</ref> The UNSC also utilizes [[glow rod]]s for similar purposes.<ref>'''[[Halo: Combat Evolved]]'''</ref>

Chemical light sticks were used by [[SPARTAN-II Program|Spartan]] [[Red Team]] to provide lighting in [[CASTLE Base]] on [[Reach]],{{Ref/Reuse|FS}} and later during [[Operation: FIRST STRIKE]] on the captured [[Taaku Xur-pattern Spirit|Spirit dropship]].<ref>''Halo: First Strike'', Chapter 32</ref>

Chemical light sticks were also used by [[Recon Team Bravo]] during a night operation.<ref>'''[[Halo: Reach]]''', campaign level ''[[Nightfall]]''</ref>

[[Major]] [[Elijah Vaughan]] of the [[Orbital Drop Shock Troopers|ODST]] kept spare chemical light sticks on his person for situations where other methods of signaling were unusable or unsafe.{{Ref/Reuse|CF100}}
