I recently decided to relocate the license plate on my new 5 X 10 aluminum trailer. It came from the factory with the plate located under the bed of the trailer where lifting the trailer caused damage to the plate and was difficult to see. I purchased the license plate light and began the process of relocation. The light now provides and excellent illumination for the relocated plate, was easy to install, and was very economical to purchase. Attached pictures reflect the finished product installed on my trailer.

Trailer Lights still work great. A nice addition to my enclosed trailer. I would purchase them again if I had too.

Great tracking and information on product status.


I decided it was time to repair the lighting on a 15 year old trailer due to several being broken, and the rest being very faded. I spent quite a bit of time on etrailer comparing options I finally settled on the 4 diode led's. I was excited to see the difference but was ultimately dissapointed with my decision to swap out the old incandescent with more costly led's as the new led lights put out significantly less light. As u can see in the pictures I did the passenger side first, then I took pics halfway thru. If u look at the driver side with old lights it has alot more light even though it only has only 2 working lights, compared to the 4 on the new side! In the front shot u can see the old on the right is casting 10 times the amount of light on the ground. On the plus side at least the orange is now orange, and the red is red instead of almost clear.

I will say the shipping was very fast, and the the customer service was awsome as always.


I purchased all new thin LED marker and license plate lights for my trailer. They look awesome and are very good quality. My order was shipped out quickly and received on time. I would definitely order from etrailer again.


I have a 2010 international trailer. I was unable to find exact match parts so I went to etrailer to find comparable parts. I found a similar license plate light. The holes lined up perfectly and wired easily.


Contrary to the appearance in the photo this light is plastic and is poorly built. The description states,"Weather-tight seal w/gasket". The lens doesn't even reach the gasket and there are so many leak points to make the statement "Weather-tight" laughable.


Much better than original that relied on the rusted out mounting frame for a ground. Yes, two wires are better than one.


A litte flimsy. Not water tight.


As always,... products are great
and all I have ordered so far is well made and looks suburb Changed out my lights for LED and I can't be happier in looks ' the Licence plate light is bright and looks good in the dark


As expected


Haven’t installed yet, but the product looks sturdy and well built.


Nice and bright. Multiple LED’s really light up the plate


Came when they said it would and was exactly the part I needed. Great service!


Good quality and very bright.


This really illuminates the plate. No more loose bulb issues, that can get me pulled over by the police. I've search for 2 years to find an LED plate light. I'm quite pleased.


I would love to give you a review but I have not received the part to my address so I haven’t seen it have you gotten a chance to look at it

I will have our customer service team reach out to you.

eTrailer is a very reputable company. They have excellent customer service, a great line of products, well packaged and quickly shipped.

This replaces the cheap plastic license plate light on a cargo trailer. It has a metal housing, is LED and is constructed much better than the plastic original. However, time will tell how the chrome finish holds up to rust. What was noticed is that there appears to be drain holes at the bottom of the wrap around lens on 3 sides. On the install, I will seal the top and side and leave the bottom for a drain. Unnecessary moisture is not a good thing. Overall a great product.

It has been a year and the trailer plate light is working great. Contrary to my original post, the housing is chrome plated plastic.and was physically an exact replacement. Occasionally, it gets bumped and the lens dislodges, but it is an easy fix with a phillips screw driver. Overall, still worth 5-stars.Paul G. mentioned the right angle mounting causing water intrusion and the weak design. On my install, i noted the possible water intrusion issue and used a small dab of silicone sealer to block the top and side slots. It has not caused a problem. Also, the cargo trailer uses the chassis as a common ground. The white wire can be grounded to the screw that mounts the light to the trailer. The trailer wiring harness white ground is grounded near the hitch

Better than what I expected. First, the purchase experience on eTrailer was simple, quick and efficient. The LED light fixture is a big improvement over the OEM incandescent unit that came with my trailer. I liked having the long lead wires to work with, too. The LEDs will no doubt out-live the trailer itself! I'd recommend this product if you're looking to upgrade your existing license plate lamp.

At one point I had to run a bead of clear silicone around the base of the lens to keep water out. No issues since then.
