Developed over many months of prototyping and refinement, this annunciator design was created at the request of simulator builders to provide a fully authentic, OEM‑matched solution. Although “Korry” is commonly used as a generic term within the sim community, these units replicate the well‑known EATON/SFARAN 582‑series indicators used across real-world Boeing aircraft.
OEM-Compatible Design
These annunciators are engineered to be completely interchangeable with real 582-series units. Both the latching and momentary versions fit perfectly into genuine aircraft panels, and genuine units fit seamlessly into these housings as well. This makes them ideal whether you're building a replica panel or integrating mixed components.
Uniform, High‑Quality Illumination
Each unit uses white LEDs to ensure perfectly consistent illumination across all caption colours. Instead of relying on coloured LEDs, which can vary in brightness, these annunciators use a tinted internal lens behind a clear faceplate lens. This approach delivers:
- Even brightness across all annunciators
- Accurate colour reproduction
- Identical intensity for any caption when driven at the same power
- Complete flexibility to assign any colour to the upper or lower segment using the same PCB
Modular & Practical Construction
The centre lenses securely click into place, preventing accidental drop-out during maintenance. The annunciator body mounts directly to the rear panel backplate, while the faceplate hides all attachment screws for a clean, professional finish.
