OEM on my Bear trailer , exact match to one that started leaking. Imagine that , just because you back it into a piling . Good price and fast shipping from etrailer. Thanks


The unit was easy to install and after one year of launching in fresh and salt water the light is still working.


I needed a replacement light for my boat trailer and this was exactly what I needed. It fit perfectly, arrived quickly, and is a high quality product.


This light is an exact replacement for the passenger side tail light on a Back Track Aluminum Trailer for an Xpress Boat. Entire replacement took less than an hour. I was surprised that the replacement light did not include mounting bolts and nuts, but old ones were in good shape, easily removed from old light and installed on new light. Overall no problems or issues.


Exact replacement. Perfect. And very fast shipping. Thanks!


Great product and super fast shipping. Will definitely return for all my trailer needs!!!




Item was not what was shown on website. Not even close. Should have returned it!

We take our pictures in house and the part should match. I will have our customer service team reach out to you.

Thus far a good light, I am using it as a rear foglight on my truck. It's been surviving the Florida rains, time will tell how it holds up to the elements, I'll write a follow up during our foggy season here. It's a bright light, not too large. My use may be unorthodox, but in the couple of weeks since I installed it still tests good.


Super quick shipping


Exactly what I needed.delivered on problems and shipping costs where reasonable. Some other outfits where way costly


Good price and product


Only received 1 tail light no packing list is the other twilight on back order 12

Customer Service will contact you.

Ordered these lights to replace the out-dated lights on my boat trailer. etrailer shipped right away. I liked that. Price was good. I liked that. Pretty simply to hook up. Plenty of wire. I liked that. They were an exact fit. I loved that. I doubt these lights help me catch anymore fish, however; the tail end of my trailer is highly visible now.

They are flawless. Everyone should change their outdated lighting to LED.

This trailer light is an LED light and should not have any problems with being submerged time and again. It was very easy to install and worked just as it should. I will not have to replace bulbs every season; how nice.

After one year the tail light is working just as it should. Been through many miles and many launches and retrievals. No problems at all.
Bert S - 05/27/2018


The light has worked perfectly since being installed. Glad I made the change to LED and etrailer was great in getting me the light, quickly! Thank you very much

Still working just fine!

As a replacement, which was the old-style bulb light, always burning out and trouble, these are great. Much brighter, stay dry and easily installed.


I haven't hit the water with this light installed on the trailer but all seems well. The only complaints I have is that the stove bolts that attach the light to the trailer were not stainless steel and the plastic backing on the light, where the square are under the stove bolts head sits is weak. If you turn the nut too aggressively you will strip the light easily. Other than that, time will tell.
I have the same make on the opposite side. Its 6 months old and is working great.
LED lights are the only way to go. Don't waste your money on incandescent lights.


It's been over a year since I installed the lights on my boat trailer. They've been "dipped" in river and salt water several times and are still doing great. The old style incandescent bulb lights, sealed even, would have burned out long ago. Best lights I have ever had on my trailer. Thanks, etrailer


This light was an excellent replacement for the Wesbar incandescent light my trailer came with. The mounting screws lined up with the old holes and the wires were color coded appropriately. I had to drill new holes for a grounding screw, other than that the installation was quick and easy. The young lady in customer service was pleasant and helpful. My only suggestion, include some butt connectors in the box, that would have made my installation even easier.


Tail light installed easily on the trailer and has worked well ever since.


Tail light was delivered, opened the box and had it installed within 10 minutes. Exactly what I wanted and works perfectly. I order from etrailer whenever I need parts for any of my 4 boat trailers and have never been let down.

Had to replace some rusted out tail lights for my boat trailer.
Figured I would try the LEDs for a change.
So far so good.

The lights came quickly, installed easily and quickly.
They work well so far. No problems

Time will tell if they hold up.


I would give 5 stars but the passenger side light came with cadmium plated bolts/nuts instead of 304 stainless steel. What does that save the supplier; $.50 maybe? That was the only disappointment. Drivers side did come with stainless steel bolts/nuts. Easy to install.


The tail lights for the boat trailer look great and work completely fine. The LED technology provides brighter lighting all around - making driving, turning, braking and backing safer in the daytime and at night!
