Re: Back-up Light
They are the same, the important part is the "T9AP1D52-48".

Use the reverse buzzer as a “trigger” to turn on the lights via use of a relay. You would run an additional 48 volt wire from the buzzer to the relay, then an additional wire from the 48v reducer powering 12v to the relay. Then the light power from the relay to the lights which would be on the 12v circuit of the relay. Thus when turning on the cart reverse buzzer it sends 12v to the rear lights. Or you can run an additional positive from the relay to a reducer input, then wire the negative or ground input, then the output to the lights. Thus the reducer is only powered and sending 12v to rear lights when buzzer is on. |

Re: Back-up Light
That is the diode drawn in the diagram: 1N4007 or 1N4004.
I like putting the diode that way as it removes any stress from the connection and you can just shrink wrapped it. |

Depending on your answer, I may have more questions. This made my head spin, but I think I figured it out.... https://en.wikipedia.org/wiki/Flyback_diode Thanks for the help Sergio! |

Re: Back-up Light
As the relay contacts close on the high voltage side it can cause a spike in the line and the diode stops the current from flowing back up the line in the wrong direction and causing any damage (especially in the long term if it does that every time it turns on).

Re: Back-up Light
Are there any concerns on soldering a diode onto those two wires (possible heat damage to the diode)?
