WW2 British RAF Yellow Wedge Cap Flash

The WW2 British RAF Yellow Wedge Cap Flash was an identifying insignia worn on the side of the Royal Air Force wedge cap during the Second World War. This small cloth patch features a bright yellow rectangular design, intended to distinguish specific personnel or branches within the RAF. Wedge cap flashes of various colors were implemented to clarify roles, aid recognition, and improve organization among RAF service members. The yellow flash commonly indicated aircrew in training—especially those enrolled as flight cadets—allowing for quick identification by superiors and fellow personnel. Constructed of durable cotton or wool, the flash was typically sewn or pinned to the cap’s left side. This artifact reflects the RAF’s structured approach to uniform insignia during wartime, contributing to the broader system of military dress and identification. The yellow wedge cap flash remains a representative piece of RAF wartime uniform history, sought after by collectors and historians interested in British military aviation.
