This is the best video I ever seen regarding how to operate a dc motor with this solenoid!

I don’t understand. Wouldn’t a DPDT switch allow forward and reverse by itself?
What if I have a 130 vdc treadmill motor controlled by a dpdt switch and I have low voltage led lights (green and yellow) that I want to come on depending on the direction the motor is turning? I can’t send 130 VDC and 30 amps to the LED’s so I need to open and close switches depending on the polarity going to the motor.
Thanks,
Paul
