Two of my turn signals were broken and hanging down but worked. I bought new turn signals that were led and replaced them. Understand now can't do that. I bought regular signal lights and a new turn signal relay. Still don't work??????

Possible reasons why the new turn signal lights and relay are not working on your Honda CB250 Nighthawk:

1. Flasher Relay Issue – The new Tridon flasher relay may be faulty or not compatible with the bike’s electrical system.
2. RPM-Related Voltage Fluctuation – The turn signals stop flashing above 4,000 RPM, which could indicate an issue with voltage regulation or wiring.
3. Wiring Problems – A damaged or loose connection in the wiring may be affecting signal operation.
4. Battery or Charging System Issues – If the battery or charging system is not providing stable voltage, the relay may not function properly.
5. Electrical Load Capacity – Installing aftermarket electrical components that exceed the bike’s electrical system capacity can cause failures.
6. Grounding Issue – Poor grounding can prevent the turn signals from functioning correctly.

To fix the issue, check the relay, wiring connections, battery voltage, and grounding points. If necessary, test the system with a stock relay to see if the problem persists.
