The Lightning Release: Lightning Illusion Flash of Lightning Pillar technique is a genjutsu that utilises lightning-natured chakra which discharges from the caster's entire body in the form of an extremely bright light to disorient their target. The caster can then further implant images in this blinding light further disorienting the victim as seen when C used this technique against Jūgo, making him see the Fourth Raikage smashing Sasuke Uchiha into the ground. This gives the caster's allies the perfect opportunity to attack the unsuspecting victim.
This genjutsu can also be used collaboratively with shinobi working together to completely overwhelm a target(s) sense of sight as seen when used by the Kumo-nin during the Fourth Shinobi World War against the Ten-Tails.
In the manga, this attack generates an electric light emanating directly from C's body, however, in the anime, though light emanates from C's body, the electricity being discharged is not seen.
