It is the right plug for what I needed it to be, I'm exited to finally recive the product and pretty fast shipping as well! Thank you


Not sure I like all this new prong connection stuff but these worked well with the new lights. Nice solid connections.

After a year, still no issues.

The item was exactly as described and works fine. Unfortunately it took 12 days to arrive by mail
Which is longer than I would have liked. I’ve done buddies with e-trailer many times so this was unusual compared to past orders. Also, when I ordered the optronics tail lights for my trailer I didn’t know they take a special
Pigtail (sold separately) to hook them to the trailer wires. Im a total novice at this stuff so it might be helpful to
Add a note about needing a special pigtail to the description of the tail lights.


Great pigtail and easy to wire up.


Great product! My right brake/turn signal stopped working on my trailer, so I purchased a new ST70RB 6-1/2" oval trailer light, along with the wiring plug and grommet, installed them in about 30 min, and it works great! The package arrived quickly and was packed nicely. I found out my fuse was blown on my 2016 Traverse for the right trailer stop/turn signal, but that was most likely from the old light which I think was leaking. I didn't know there was a fuse just for that so I learned something new. I will definitely purchase trailer products again from!


The lights and 3 wire pigtail were excellent, but the rubber mounting grommet would not fit the opening. Had to use original grommet.


With the trailer lights you really need this PIG TAIL. You can make it work, but this is so much easier and is water proof.
Picture is back side of the panel where the PIG TAIL is sticking threw. This will get coated with under coating when it all done.



Quality parts, fast delivery


Everything you would expect. Fast, friendly, and very helpful.


Outstanding customer service, very professional, and I will be using your services again.


I really like the bright back up lights. It does take a little extra work for the back up lights. - Sorry this pic doesn't show the backup/stop lights but this is the great little chuckwagon we put them on.


Was required with the light I bought. It worked well and made the install clean and it is easier to get to the wires.


Lights were a perfect replacement.


LED lights are the way to go. The reflective marker lights are great for times when the lights aren't on yet headlights will reflect off them letting the driver know there is something there. The only thing would be better on these lights would be a better ground.

Working well. One of the marker lights has a hard time keeping grounded.

Tim - 05/11/2022


Lights fit perfectly, as did the grommets them self


Exactly what I ordered and a timely fas hion

Works fine
Kenneth - 04/11/2022


Pretty simple to get on etrailer. Try finding this socketed connector anywhere else without having to buy the entire enclosure. This is just one of about 24 items I have purchased from and even when i screw up they get me right.
They seem like very nice folks who care that you get what you need.

Never better, I have another trailer to rewire and etrailer is where I am going.
Jon W - 10/19/2016


Just as represented; worked perfectly.


I ordered more parts (lights for my motorcycle trailer) than really needed but now I have plenty of spares. These parts were exactly what I needed and were very reasonably priced. The shipping was quick and the order was filled correctly.

Great Job !!!

My trailer is still working great. Thanks.

Great product and I received the product very fast.


Used with Optronics Turn/Tail/Stop LED assembly: Not really much to say about a plug except that this one does what it should and has had no comebacks to spoil the project. Perfect pin alignment with firm pin fit to light assembly. Molded rubber plug body fits snugly into light housing but is easy to grasp and remove when necessary - a good balance of 'in forever' but 'removable if you need to'. No evidence of hardening, cracking, or deterioration of plug body.


I ordered the STL101RB Trailer Tail Light - Stop, Tail, Turn, Backup - LED to replace the standard tail lights on my Yamah Drive G19 golf cart. They replaced to stock ones perfectly as a neat way to add a backup lights for a custom feature. The backups led are actuated by the reverse switch on the dash.

It should be noted that the ground terminal on the two wire pigtail connection is not wired internally to the backup LEDs. They rely on the ground supplied by the three wire pigtail. Not a big deal, but worth noting. It throws a curve when bench testing.

These lamps add a nice custom touch!


I replaced the conventional lamps in my 1990 Peterbilt Midranger box truck. The change out was easy. The previous lamps were troublesome because of vibration, moisture / road salt, causing them to not light. I used these pigtails to plug into the LED lamps I purchased from eTrailer, to easily install the new lamps, splicing into the existing wiring harness in the truck. The thing to know, is the unique color coding: White is Ground, and has a convenient lug on it to attach under one of the mounting screws. Red is for the stop/turn signal, and Black is for tail lights.
