Possible Causes
Miswired flashing light output, Wrong type of light (non‑flashing on flashing output), Stuck relay/triac on Nice board, Accessory wired to constant power instead of controlled output
How to Fix / Troubleshooting
Safety first: Turn off power before working on light wiring.
- Verify wiring terminals: Ensure the warning light is connected to the correct FLASH or LAMP output terminals, not directly to mains.
- Check light type: If the output is designed for a flashing beacon, use a compatible Nice flashing light or self‑flashing beacon.
- Test with known‑good light: Temporarily connect a test lamp to the output to see if it behaves correctly.
- Inspect board: If the output is stuck on or off regardless of commands, the control board output device is likely faulty and the board should be replaced.
