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.

4" Waterproof light displays brake, tail, and turn signals on your trailer. It mounts with the built-in flange and has a weathertight connector.

Perfect replacement fitment and excellent price.
Nothing like ordering a product, waiting for it to arrive, only to discover it's useless without another part that's sold separately. You cannot wire this without an additional pigtail. This is the second time I've received a product from etrailer that required something else to be bought separately....

You are correct, this LED Trailer Tail Light requires a pigtail to wire it in. Part # AL45PWTB to fit industry standard 3 prong plugs or part # A45PMB for the hardwire version.

Easy ordering and fast delivery. Only thing I will add is that the wiring connection on the back was different than mine and I had to order the connector harness that plugs into this new light and the old connection on my trailer. I don’t think this was mentioned in the product info. All is good! Thanks
Just what I needed to replace the old lights on my tow dolly. I had to make the holes slightly bigger to fit the unit in, but I’m hoping I won’t have to replace them again for a long time.
Very bright, really like the weather tight connectors.
Perfect fit but connector has changed and you need to purchase Item # AL45PWTB to eliminate need to cut and splice factory wiring.
Worked great. Improvement to old style bulb lights!
Was a perfect replacement for the old burned out lights on my Featherlite stock trailer!!!
Light has worked great as expected! No issues and was direct replacement for original light.
Fast service! Will use again!
I can't believe how thin and cheap this plastic junk is, for the price I thought they would be professional grade. They don't even include the plug that is required to install them.
Order was processed and delivered quickly. Exceeding my delivery expectations for ground. Continuous follow up on the order. Savings was great. Definitely will be back.
Thanks I received everything and it was what I expected. As I do more work on trailers I will be a returning customer.
Good customer service
No gasket with light. The white lights I ordered had new gaskets. Had to use old gasket
