These lights have complete functions, running light, brake, reverse, and a more safer and clear communicating amber turn signal that even is sequential to the outboard side of the trailer to the direction indicated if mounted properly. I seem to find the obscure things, as I cannot find any other light right now with this function in this form factor. This is likely due to the fact most trailer wiring is not set up for a separate turn signal circuit. An amber signal provides much safer and clear indication of where you wish to go. The combined brake/turn circuit is simply convenient, but may be somewhat initially confusing to some people. Yeah, yeah, I know... It's not that confusing....but remember some people are not all there today. To achieve a dedicated turn circuit with these lights, I am currently wiring in a curt converter. (CURT 56196 2-to-3-Wire Splice-in Trailer Tail Light Converter for RV Dinghy Towing , black https://a.co/d/gjAhztK)I went ahead to go through the trouble of doing so based on the fact I'm rewiring the whole trailer anyway, so I might as well. I am also indeed adding a wire for reverse light functionality as I did not have that currently either. To not have to touch the vehicle wiring and to have the feature work with any vehicle, I wired the curt converter on the trailer itself after the vehicle trailer wiring. My trailer is set up with a 4 pin and 7 pin connection for convenience, all at once. Wiring is simple. You need one extra wire to the rear lights for specifically brake functionality. This will connect to the red wire on the converter. The regular green and yellow wire outputs will now be dedicated turn signals rather than combined brake/turn. You can either mount the converter on the trailer tongue and run a new wire throughout the trailer, or mount the converter closer to the rear of the trailer and run a shorter new wire to each light. It's pretty simple. You will then have dedicated brake and turn signals. Also, if your hazards are on, the converter will flash the brake lights which is normal. The converter will not be able to know it's hazards with both left/right sides energizing at the same time. It will put it in brake mode and send power through the brake wire.With all this said, I have not fully had a chance to fully test these lights, but they certainly look well constructed. They fit in the rubber grommet mount as well as bolt on. They also do not include the usual light connector socket. These will need wired in, either directly to your harness or by wiring in a connector of your preference for easy removal. If anything goes wrong with operation with these lights that is a defect of the lights themselves, this review will update.
