This indicator unit is part of the warning and emergency services system. Its key function is to display warnings upon issues or faults occurring, deemed as "less critical" than those displayed by the S.W.P (standard warning panel), and has one control:
| Switch | Title | Description |
|---|---|---|
| "T" | Indicator lamp test | Press to test all lamps |

| CAN | Canopy unlocked |
| ICE | Ice detected |
| GEN | Main DC generator failure |
| FUEL 1 | Fuel pressure low, No. 1 engine |
| FUEL 2 | Fuel pressure low, No. 2 engine |
| OIL 1 | Oil pressure low, No. 1 engine |
| OIL 2 | Oil pressure low, No. 2 engine |
| AC | AC generator power failure |
| TURB | Turbine stall |
| HYD 1 | Hydraulic pressure failure, No. 1 system |
| HYD 2 | Hydraulic pressure failure, No. 2 system |
| TTC 1 | Reheat temperature high, No. 1 jet pipe |
| TTC 2 | Reheat temperature high, No. 2 jet pipe |

The unit being used by this project has a handwritten note of "452 UNIT OK" - if the 452 means T Mk.5 XS452, then this could originally be from the first Lightning I volunteered on at Cranfield!
SIMULATION
The logic for most of the systems that illuminate the auxiliary warning captions is already scripted, but an interface capable of driving 80 mA into the double lamp circuits needs to be designed (40 mA per lamp).
