Question: Will this work with a trailer that has LEDS
Document: This converter simply works. It comes with easy to follow instructions. I'm using it on a 1989 Suzuki Sidekick with extra lights on the rear of a custom hardtop. I also use it for towing and the trailer turn signal lights now work correctly.
Active converters require an extra power line coming from the battery which is used to amplify the signal that the tow vehicle is creating. Because of this, the trailer lights will work the same as the tow vehicles.Obviously the active converter is better, but if you are on a budget like I was this is probably good enough. Just make sure that you activate your turn signal a couple seconds earlier than normal (especially if your vehicle lights are being blocked by the trailer).
It work very well
I have a 2012 Harley Davidson Road King. Bought a trailer to pull behind it and this converter works great.
Great solution for wiring in a common trailer with independent tail lights. Seems pretty sturdy and I don't expect to have any problems with it. Much cheaper than other options.
This light converter works well. Hooks up easy. I like the converter box at the end of the wiring harness with trailer plug-in incorporated into it. It eliminates additional splicing.
This thing didn't work right out of the package....it's not even worth it. I found out I could get a much better converter from U-Haul for just a few dollars more....
This product worked as described, and allowed me to legally pull a trailer, and after installing it, I learned about active and passive light converters. Since this is a passive converter, it simply splits the signal for each light which works great for everything except for blinkers. Since the current on a blinker circuit is more limited, the trailer turn signal is very week and takes a few seconds to ramp up.
This is a WARNING regarding the poor quality of this product. The ground connection on the module plug (the silver male connector) is very weak and snaps off very easily. Recommendation is to use an extension as your final plug to trailer wire. Keep the module from being constantly unplugged, this will keep the connector from snapping off.I gave it 3 stars because it does until the cheap connector broke off. Cheap price, Cheap quality.
Adapter worked as expected. Delivery was FAST. I first tried the Curt adapter C55309 made for the 2004 KIA Sedona but it would not work correctly. I bought a second one thinking that the electronics were bad, but second one did not work either. I used the T-connectors from the Curt adapter and it made the installation a snap.
Answer: i have 2 off these hooked up to LED bar brake lights on a Nissan Frontier and Chevy Colorado, they work fine.
