A Hayward OmniPL relay clicking without powering the pool lights could be caused by several issues:

1. Faulty Relay – The relay may be clicking but not making proper electrical contact to pass power to the lights.
2. Wiring Issue – Loose or incorrect wiring connections between the relay and the pool lights.
3. Tripped Breaker – The circuit breaker supplying power to the lights may be tripped.
4. Burnt-Out Lights – The pool lights themselves may be faulty or burned out.
5. Low Voltage or No Power – The relay may not be receiving proper voltage from the high-voltage panel.
6. Defective Circuit Board – The circuit board controlling the relay may have a malfunction preventing proper power distribution.

Testing voltage at the relay and checking wiring connections can help diagnose the issue.
