My bike fell over and the left turn signal has to be replaced. So, with new turn signal in hand, $42, I began removing what was left of the old one. Unbolting the remaining piece was no problem, but when it came to disconnecting the plastic connection for the wires, it would not come apart. So, what is the trick? The new wire definitely matches the old, and I can see a little square nub which I assume clicks in somehow, but how do you get it to disconnect. I ended up cutting the connector off the new light and connecting the wires to the old, still connected wires in the old connector. It will work, but I don’t like being defeated by a small plastic connector.
