## Questions & Answers

**Q: Maybe this is a dumb question but why are there 2 inputs and 1 output?**
A: 1 input is from the towed vehicle, the other is from the towing vehicle. The output is to the light on the towed vehicle

**Q: How much does the voltage drop from the input to the output side of this diode?**
A: Not measured, but this type of diode typically drops 0.7V.

**Q: I have light bars on my rack and pods in my bumper for reversing can I use this to turn on all my lights but still only use the pods when I backup**
A: I really have no idea. You must consider just what the diodes do and figure it out yourself. 
Each diode has 2 wires in and one out. The outgoing wire goes to a vehicle light. The incoming wires: 1) to the ‘normal’ source 2) to a new or secondary source. The purpose of the diode is to prevent backfeed between the 2 sources. 
Now with that in mind, can you answer your own question?

**Q: Can this be used to run a led tow mirror light. For a turn signal/marker light? So the same led light can be used as a turn signal and marker light**
A: These items only let power run one direction. If you had your tail lights on and also tried to use the bulb as at turn signal there would be no flash as the light would already be on steady for the tail light. Hope this helps.

### ⭐⭐⭐⭐⭐ 







  
  
    Great product
  

*by R***G on Reviewed in the United States on 19 August 2023*

I used these to correct a high-beam issue that I was having with some headlights I purchased. The units are well made and have been working flawlessly on a daily basis for a few months now.

### ⭐⭐⭐⭐⭐ 







  
  
    Works!
  

*by H***S on Reviewed in Canada on 16 November 2022*

Used this to power a 12v refrigerator with batteries and shore power when connected without back feeding the 12v panel. Works like a charm.

### ⭐⭐⭐⭐⭐ 







  
  
    Great addition for lights!
  

*by S***M on Reviewed in the United States on 11 July 2023*

These work great when you want to add rear lights. It helps the process of having the added lights work in reverse and on a separate switch so you can use them on the fly! So easy to install!
