The light and adapter works great. I made a custom brake light for my motorcycle.
Remember to get these with the tail lights if you are replacing old system lights. The plug make wiring much simpler and the connection water proof. The lights that these fit work very well and look great!
Coverted from the three round pins I had, to a rear tail light with three flat pins. Both ends were female. Nice easy fix. Thanks.

The products I purchased from you a year ago work very well and expect they will for a long time. My lights on my trailer work perfect. Soon Im going to add more for visibility and I will get them from you. Thanks!
I was very happy to see they made this plug, versus having to do some homemade connections with my heat shrink tape and connectors, hoping for the best. This wiring harness pigtail not only is completely waterproof on the weather end, but is the high quality rubber & plastic you would expect to find on a brand new vehicle. Wouldn't hesitate to recommend this to anyone.
Works great, quick shipping and at a good price

Works great
Great product. These pigtails are great for the LED lights And brackets I put on my utility trailer.
Install the new glow lights right when I received your package in the mail. It was easy to install all four lights in less than thirty minutes. They look great when on. Now I need to do my marker lights so they all match. Thanks.
Great lights and pigtails made installation super simple. Would definitely buy here again.
Product worked great on my new 2020 Peterbilt 567 tail lights.
Thanks for asking, I really appreciate the follow-up. The item I ordered is exactly what I needed and delivered in a very timely fashion and might I add very reasonable shipping.
Resists water, corrosion and uv damage like a charm on my Baja bug, made the process of swapping out lighting options during my projects build a breeze! Great product, survives the harshest wet and dry environments!
Was a perfect replacement for the old burned out lights on my Featherlite stock trailer!!!
Made it easy to wire my LED lights. Very good and helpful product.
Plugs worked great. Good product good seller fast shipping
I'm very happy with my purchase. It meets my expectations. Thanks. I'll be doing some more purchasing in the near future.

This 3-wire pigtail has a female plug on one end that pairs with the weathertight connection on the back of your Optronics light. Color-coded wire lead is 10" long. Designed specifically for lights that provide stop, tail, and turn functions.

Very nice connectors. Water tight and had dielectric grease already in the connector , perfect for wiring my new l.e.d taillights
The video was very informative and the item looked like it was correct, so I placed my order. The package arrived in timely fashion and looks like good quality. The pigtails will help to complete my project for tail lights on ten EZGO golf carts.
I used on my UTV to upgrade lighting.Excellent product,fast shipping and quick response to a question I had. Highly recommend
Replaced my vintage trailer brake lights with the LED Optronics and these pigtails made it an easier install.
Very helpful
These were installed on a box truck that had no side markers. They're extremely bright and make the turn signal quite obvious to drivers in other lanes that cannot see the rear lights. These were a major improvement in safety for our truck.
Great product, Super fast shipping
I stretched out a pontoon trailer and added an extra axle. Ordered wheels , tires , tail lights and marker lights from etrailer and received all my order very quick and everything was great. The service is outstanding
I purchased a set of Optronics One LED tail lights (stl003rfb) awhile back for an upcoming project. I guess I had not read all the details. There was no wiring pig tail. Not much good without them. Rec'd and installed them this eve.. Brake light bright enough but running light quite dim. Description says "DOT approved", but just for safety I must replace them.
Pigtails were fine though.
when I ordered the trailer lights your website should have told me that it takes 2 different pig tails to hook up the lights .I waited for my order only to find out that I need 2 different sets. Not only did I have to postpone my installation I had to order 2 more pig tails and pay additional shipping. Good product. Maybe show the back of the lights on your view and people will see that you need 2 sets of wiring!
One year after installation, these lights are still going strong. The visibility of the brake/turn/tail lights is exponentially greater, especially at longer distances on the interstate and in the daytime.
Worked great with the waterproof tail lights. Been in use for over one year with great performance.
The brake lights I ordered online for my travel trailer arrived on time as promised. When the original model I ordered wasn't available for 3 months, they suggested an alternative that was available that fits and works perfectly. Great service.
They worked
The pigtails are great, however being that this is the only method of connection, they should have been include with the LED lights that I purchased.
Good quality, etrailer is great to do business with!
I used these instead of the adapters that had two connectors. Cheaper and worked perfect.
Shipping has been faster than that website named after that South American river. Orders were 100% correct and they had what the other place didn’t and at a great price.
I love etrailer! I trust their value, choices and customer service which includes product videos. These were on time and the quality was great!
I plugged it in and it worked. I'm frustrated that it's not included with the lights in the first place.
Thanks I received everything and it was what I expected. As I do more work on trailers I will be a returning customer.
Electrical pigtail as always part is great quality as described no issues whatsoever
Been on my trailer for a year and have had zero problems
All products purchased from this retailer have worked as advertised
Fit tight into light socket
The light and cord worked great....than ks
