Smart diodes allow a motorhome that is towing a car to use that car's rear lights if the car has variable voltage LED lights. Unlike regular wiring diodes, smart diodes activate only the intended circuit - brake lights or tail lights.
Features:
Smart diodes allow a motorhome that is towing a car to use the vehicle's rear lights, provided it uses variable voltage tail lights. Variable voltage tail lights use the same wire to power the brake lights and tail lights. They do this by using a 12-volt signal for brakes and a 9-volt signal for tail lights.
If a regular wiring diode is used with variable voltage tail lights, then the bulb will light up as though the vehicle is braking whenever the tail lights are on. That is, you can't tell the difference between the brake lights and running lights. Smart Diodes correctly modulate the voltage to activate only the intended circuit. The result is vehicle lighting that looks and functions as intended.

Unfortunately replacing the stereo did not fix my left tail light issue. I fear it's a possible wiring issue and unfortunately I live in Arizona and there is no e-trailer down here for me to take it to for repair. I would imagine the new diodes are perfectly fine
work great and easy to install.
I had to develop a method to make them work for my 2015 Ford Edge SEL.
The diodes have functioned without fail.
Great service and great job keeping us updated with the transit. We will definitely shop here again! Thank you.
Worked as advertised.
There needs to be more clarity on which ones are needled to work with vehicles. I ordered the kit that has more diodes. After opening the kit and called the help line and was told it will work. So I even emailed asking to order the smart diodes if they could discount them because I already opened the package on fist order and I could still use the rest of wiring. No response so I just ordered the right ones. There is no room for more than one diode.
Easy company to do business with.
The dealer installed the wrong diodes for our tow set-up and our lights never worked properly. Looked on etrailer and found a how-to video that explained the problem, ordered this product (the correct diodes), and now everything works just as it should.
They work great and are a nice compact size. However, the instructions on the packaging is different than what is shown on the actual device leading to confusion.
installed fairly easy ,once i got wiring diagram for 2020 jeep gladiator/with LED lights LED tail lights need smart diodes ,not 4 reg diodes
Great service, when I called they were very helpful
Thank you!
This product works very well but the wire diagram was not correct.
Works like a charm!
Perfect besides packing is all bent up
