Curt 2 to 3 Wire Tail Light Converter

i used this on my trailer so that i was able to use taillights with separate (amber) turn signals, it works like it is supposed to, BUT it doesn't work with LED tails bc it drops the brake wire voltage coming out of the convertor to 10v causing the brake light LEDs to not function properly; i solved this issue with a voltage regulator (10-32v in - 13.8v out) so if you've got a little wiring knowledge or are using incandescent taillights then it will work great for you. 651911

so far its still working just like it did since day one, no complaints so far.

The unit came quickly and was really easy to wire with the instructions.1665592

This item was the perfect solution to a recent situation where a manufacturer changed a trailer plug. This adapter allows us to now pull there trailers with brake lights1486086

1 Tail Light Converter - C56196 :
i was a little confused, but finely figured it out.
2 Tail Light Isolating Diodes (Qty 4) - 48955 :
i was told i would need these (their for towing a vehicle, not a trailer)
etrailer salesperson should had known that(they were told)
wasted money, cost to ship back 139740

I used this device to wire lights on my back rack. I wanted the turn signal and brake lights to work independently. On my truck the brake and turn signal are the same bulb. It works great!1321388

Product worked great and finally resolved my vehicle wiring issue.1485147

Works great for stop/turn/ tail lights with yellow signal capability on my sled deck, only issue is when hazards/brake lights activate there is a short flash of yellow before the electronics take over. Great solution for the price.913661

Still working good, no issues yet!

I had a little issue making this work on my motorhome, but Tammie was great and we figured out how to make it work for me application.1383541

I used this product to wire the center, high-mounted brake light on a pickup truck camper shell. I used the wires from the rear brake lights. All I can say is that it works like a charm. It does exactly what it's supposed to do.745228

It’s still working like a charm.

It works as described under normal circumstances, but I have one problem with the hazard flashing.
Using it makes the brake lights light up on my trailer and not the turn signals like on the car.
I still have to do some research on that issue.421306

Hi, Still using it and Im happy with it.

I found a camper shell for my Ranger that had an LED brake light, but it had never been wired up before. Before I found this product I had simply spliced a connection into one of the vehicle's brake light circuits. While this DID work, it also meant that it would flash the turn signal from the side that I wired it into (I used the left side; Ford used amber turn signals on the Ranger from 1993 to 1999, but mine is a 2011). This would have confused anyone behind me whether I was slowing down, turning, or both with too many flashing lights at once. This tail light converter was the solution to this problem. An ordinary converter (3-to-2 wire) will NOT work b/c it can't be wired in backwards (tried it before on a similar project). Same for this one (it even says it on the labeling) except it works in the opposite direction (2-to-3 wire). I wired it in the same way as just the light itself, & nothing happened. Eventually I found out it needed power from the left AND right brake lights for it to function. EUREKA! Everything lit up when I pressed the brake pedal. I also found out that the hazard flashers run through the brake light circuit in the converter after being separated from the turn signals--the brake light still flashed along with them (but ONLY them); the same thing happens with the high-mount stop lamp on my Wells Cargo trailer, so I can live with that. Had to find extra wiring to reach the right side though. Only suggestions are to make the the input wires longer & explain in the instructions that you need the left AND right inputs for the converter to run properly. Otherwise an excellent product!552854

Does what it says it does. Internally, it uses a relay that triggers when both turn signal inputs are activated, so there is a pulse on the output when hitting the brakes, or when the cautions are activated.

I used this to install turn signal / marker light combos on my trailer. This stops the brake light functionality from lighting up the turn signal portion of the marker lights, but there is still a brief pulse or strobe when the brakes are hit, or the cautions are activated.

I would have personally used a mosfet in this unit instead of a relay, as the switching and signal processing would be orders of magnitude faster with no pulse or strobe effect.

So, it does separate out the brake lights from the turn signals, but not 100%, more like 95%388962

Used it to wire up a third single brake light bar on a teardrop trailer. Works well. OEM trailer lights are LED which necessitated the choice of this controller over the standard controller. Written and graphic wiring instructions posted by etrailer were easily followed, and so far, after a year of use, no issues. Thanks.640215

This item is exactly as advertised. I use it to convert a U.S. Spec vehicle with red turn signals to pull a E.U. trailer with the yellow turn signals and works like a charm. I have ordered several times from this company and continue to receive excellent service from the ordering processing all the way thru to the delivery.
Would recommend both this product and the company to anyone asking.

After one year this is still working strong with no issues. Very good quality.

The tail light converter works as it should - make sure that the ground wire is connected solidly then you'll be fine . Specially on boat trailers that could cause issues.
The ground wire is the first to corrode and suddenly nothing is working any more.
I greased all the ground wire connectors- also on the vehicle side ....891746

Purchased a set of European style taillights for a trailer rewire I was doing. Got everything wired in and couldn't get the taillights to work properly due to they had a 5 wire configuration, after some research found that over seas the turn signal and brake signals are separated on trailers, in the states ours are combined on one signal wire, thus they're wasd no way to make these lights work, until I stumbled upon a forum and there was a link to etrailer and what do you know here's this little black box that does what I need. I ordered it but yet was hesitant cause I really didn't think it would work. Once installed all works perfect. I stil got to use my taillights I wanted on my rewire and everything works just as normal. 711304

Does exactly what it says, converts from combined turn signal/brake light to separate turn signal and brake light circuits. I am using it to pull a Bushtec motorcycle trailer (with separate brake light circuits, 6-conductor flat connector) with a motorcycle (with combined signal and brake light circuits). I just hooked it up in conjunction with a circuit isolator I already had wired in to a 4-condoctor flat harness tonight and it works. So now I have the 4-conductor connector for a rack I use instead of a trailer sometimes and the 6-conductor connector for the Bushtec trailer. The only drawback I have found is the third brake light on the spoiler of my trailer dims if I am braking and signaling a turn at the same time. It does this each time the signal flashes. But for the price, I'm happy with it. 294423

The purchase was very easy. After the post office did not deliver my first order I reordered and paid extra for UPS shipping. UPS left the package at my door and everything is good. 257536

Installed on my Yamaha Venture. Everything is working after the first year.

This convertor did exactly what I wanted it to do. The wires were clearly marked which made for easy installation. I rewired my trailer and wanted to put yellow turn signals on along with the red brake lights. I was able to use a standard 4 wire plug to my vehicle and the convertor did the rest. 194298

Worked great, used to convert trailer plug into a workable connection for the third light on my camper shell and with a y connection I can still attach trailer wiring. Thanks770601

I recently purchased a new CanAm Spyder and had a trailer hitch installed to pull my small camping trailer. The Spyder output cable has combined brake and turn signal connections while my trailer has a separate turn signal and brake hookup. After calling Etrailer and speaking with Rick about my problem he suggested I use the C56196 converter. This small unit was exactly what I needed and it works perfectly. 186172

The CURT 2-to-3 wire conversion kit was easy to mount and install.
Upon fist glance, there seemed to be an issue with the quality of the plastic box, and where the seems did not meet. However, the longevity of the part is yet to be seen. The converter was marked clearly, and instructions were good.
I used the converter for a Swedish boatwashing machine that was imported into the USA. The European style connector was removed, and the CURT conversion kit was wired in. After wiring up the inputs and outputs as labeled on the part itself all lights worked independently just as they should. Great product with ez to understand instructions and works as it should. 695277

The product worked very well. Was able to adapt the trailer wiring to the motorcycle wiring very easily. 366691

both units still working and I am very happy with them.

Easy to install and worked as advertised. Installed on 2014 Honda CRV. All diodes and converter were installed inside tail lights vs. removing inside panels. Saved hours of work. 150113

C56196 is great to separate combined brake & turn signals. I could find it only at etrailer. I used the backup lights as the new turn signals.
I put a b.u. light on bumper.457984
