Trailer Taillight Converter

I have been having trouble finding one of these that actually works and this one does. I have normal 7 pin wiring from my truck and wanted to separate the turn signals on my trailer for my newer led tail lights. This so far has worked like a charm. Brakes, left turn, right turn, flashers. Everything works. I did not hear any buzzing noise, although there was a clicking when the flashers were going. Sounded like a normal flashing relay. The only thing I did notice during heavy testing was some times when applying the brake or letting off the brake while the turn signal was on, the other turn signal would come on for about a 1/2 second. But it works great and I am keeping/installing it permanently. I also really like that there are mounting tabs so I can secure it to my trailer.

Super easy to understand directions and easy to install with or without any basic wiring experience. Comes with wire taps that you splice directly into existing wiring. (I went overboard and built a small junction panel to make it easy to swap out leads. (Plus I was stripping/replacing the old wiring as this was an old trailer.)) I DID discover that the way *I* have my lights modified, the replacement LED bulbs in the original brake fixtures would cause the *ADDED* second brake LED strip lights to stay on when the running lights (constant-on trailer marker lights) were on. BUT this was only affecting the additional LED strip lights, and not the actual two way bulb. For now, I had to use the standard incandescent bulbs in the original fixture.

I used it to build a standalone brake light on top of the self made truck cap, feeding the output from a trailer plug through this device to the brake light. I had to add 100ohm 1w resistors from each of the turn signal leads to the ground, else the truck complained about a light out. It was important somehow not to mix up left and right wire - truck complained when i did. The buzzing is due to PWM emitted by the truck - maybe if I had simulated incandescent lights with 1ohm powerful resistors it would have tricked it, but i have none so I live with the buzzing for now. I it must be a relay (actually 2 relays) inside the unit which buzz. I might add a capacitor + resistor filter to smooth out the pwm.

Good product, divides out break lights from turn signal wires. In my case, I added amber turn signals to my camper trailer and this did the trick. I was able to mount and install at the rear of my rig and didn’t have to run extra wires front to back making install a breeze.

I installed this thing to my trailer. Matched up all the wires according to the instructions It’s pretty straightforward. After wiring it all up I went to test it out. The unit itself made a loud buzzing noise when you press the brakes. The lights and signals work as it should but the BUZZ noise felt like it was ready to fail me.

Used for a third brake light in a topper on a 89-00 GMC truck. Comes on when I apply the brakes, as it should. It annoys me when these trucks have the topper 3rd brake light hooked to one of the brakes lights and it flashes when you signal. Only issue with this truck, this module also turns on when I use the hazards, which works out because of the rapid flasher I added to get the attention of the people behind me. So when I turn on the hazards the third brake light rapid flashes while the hazards are lit up. All said and done, it has been on the truck for a couple months and is functioning properly. I would recommend this product.

Worked exacly as expected. I was converting from my 4 pin trailer plug back to amber tail lights for our bile rack. Worked great!

Works perfectly for the trailer lights. Good instructions and well made. No problems so far. I recommend it.

Originally bought another brand of module/circuit to hook up the brake light on the canopy for my 2003 Dakota and that did not work. Read the positive reviews and thought I give this a try. Well the good news is that it worked. Hooked up the three input lines and then hooked up the output brake line from the Carrofix module and a separate ground wire to the canopy brake light and it was ready to go. You do not need to hook up the output turn signal wires from the Carrofix module for just the brake light to work. My only complaint was the size of the module itself. Now lets see how long it will last.

Missing a star for the price a bit high and the pre cut cable end could be longer. Other than that it did the job ( with led flasher)

Works wonderfully, but you MUST make sure your common ground is good.

The box began to “glitch” just 3 months after installing it. The signal lights would come on randomly and I traced it back to this box. I contacted the seller who told me I’m out of luck because I’m outside the 90 day exchange policy. If I bought local most of these items have at least a 1 year exchange. I will refrain from buying anything such as this from Amazon again, no matter the seller.
