There are usually two components to a light bridge: a control panel, and the light emitters. The control panel is a semi-translucent holographic array of [[Forerunner symbols|Forerunner symbols and glyphs]] that are projected over the surface of a pedestal. Though a variety of control panel configurations have been observed, in the case of one of the light bridges on [[Installation 04]], tapping the "blue-green circle" activated the light emitters.{{Ref/Reuse|tf}}

A cascade of coherent, high-energy photons are emitted through the air, generating a visible, horizontal band of light. Through unspecified physics, the coherent band of light interacts with the illuminated air, and pushes aside the air within and around it it, becoming a firm, solid mass capable of supporting extremely heavy weights, ranging from an [[M12 Light Reconnaissance Vehicle|M12 Warthog LRV]] to several [[M808B Main Battle Tank|M808B Scorpion MBTs]].<ref name="ark">'''Halo 3''', campaign level, ''[[The Ark (level)|The Ark]]''</ref><ref name="covenant">'''Halo 3''', campaign level, ''[[The Covenant (level)|The Covenant]]''</ref> When damaged, the emitters flicker on and off, causing the light bridge to flicker, creating a less stable force.<ref name="gs">'''Halo: Combat Evolved''', campaign level, ''[[343 Guilty Spark (level)|343 Guilty Spark]]''</ref>

Light bridges are commonly seen on most Forerunner constructs. The [[Relic (location)|Forerunner complex]] on [[Harvest]] featured light bridges crossing over a series of chasms surrounding the center of the main chamber. These were used by the UNSC forces as they made their way in and out of the facility during the [[Harvest Campaign]] in [[2531]].<ref>'''Halo Wars''', campaign level, ''[[Relic Interior]]''</ref> [[Trove]], discovered by the {{UNSCShip|Spirit of Fire}} in the same year, had a multitude of light bridges to span chasms within its interior. Unlike most light bridges encountered by the UNSC, which manifested as simple beams of blue-white light, these light bridges featured arrangements of lines forming symmetrical, geometric patterns characteristic of Forerunner art and architecture.<ref>'''Halo Wars''', campaign level, ''[[Beachhead (Halo Wars level)|Beachhead]]''</ref>

Light bridges were used by John-117 during the UNSC's operations on the surface of [[Installation 04]], in the [[Halo (Halo: Combat Evolved level)|subterranean complexes]] and the [[Flood containment facility]].{{Ref/Reuse|tf}}{{Ref/Reuse|gs}} Though mainly unseen on [[Installation 05]], they were also present on [[Installation 00|the Ark]], again in a [[The Ark (level)#Forward Unto Dawn|subterranean area]],{{Ref/Reuse|ark}} and another one at the entrance to the [[Installation 00 Citadel|Citadel]] near the Ark's [[Strip mining moon|Core]].{{Ref/Reuse|covenant}} Light bridges were also present on [[X50]]; some of these bridges were crossed by [[Spartan Operations|Spartan]] [[Sarah Palmer]] during the [[Battle of Draetheus V]].<ref>''''Halo: Spartan Assault''', ''[[Operation F: Hydra]]''</ref> The [[Promethean]]s' shield installation [[Requiem]] and the [[Didact]]'s ship, ''[[Mantle's Approach]]'', also contained a great amount of light bridges.<ref>'''Halo 4'''</ref> During the [[New Phoenix Incident]], [[Cortana]] and several of her rampant copies were able to manifest hard light holograms of themselves from a light bridge and create hard light shackles that temporarily bound [[Ur-Didact|the Didact]].<ref>'''[[Halo 4]]''', campaign level ''[[Midnight]]''</ref>
