Put new flasher in makes a fast noise?

If your new flasher is making a fast clicking noise, it typically indicates a problem with the circuit, such as a burned-out bulb or a poor connection. This rapid clicking is the flasher's way of signaling that it isn't detecting the correct load. Check all the turn signal bulbs and their connections to ensure they are functioning properly. If everything seems fine, consider replacing the flasher unit again, as it might be defective.
