I have built a elaborate modification to a old truck turn signal Adding a pin under the steering wheel contacts two switches in the turn signal body Then through a series of ladder relay logic - because I didn’t want to add any transistors to my truck - the relays will hold the signal until the steering wheel makes at least a half turn before returning to its home center and only when home do the signals auto kick out. Photos of my crazy turn signal project below, the system is waiting for paint, this old turn signal was fairly unique and I liked how it looked.
A much simpler solution would be adding two bright turn indicators on the steering wheel that cannot be ignored Reminding you to turn off a manual signal -s
