I was impressed that when I called to check on my order I didn’t have to wait to talk to someone and my questions were answered immediately. Great service. I will use etrailer again based on this experience with them.


worked perfect! Thanks.


work great looks good on my trailer


I bought a pair of these to replace a set of trailer side markers. Simple to install and came with a set of sheet metel screws. Just orientate the base housing keeping the weep hole at the bottom. Plenty of lead lenghth to work with, too. Overall, these markers provide very good illumination.


I searched for 2 1/2" red and amber lights for some time, before being introduced to These lights were a good fit for my project, restoring a camp trailer, and they were very reasonably priced. Once ordered, customer service was in contact with me until my order arrived, via email. Great follow up!

Happy New Year! Yes, I did purchase and receive the lights. They have been installed and work well. The trailer that I was working on, was a restore project. I couldnt find any lights that were an exact OEM part, but with a slight modification, these worked out well. And they look great!

Exactly what I needed down to the mounting holes. Easy to install, matches existing lights.

I am well satisfied

Just what I needed.


I couldn't find these for my old camper in local parts stores. They were perfect fit and replaced the old parts perfectly. Work great. Thanks E-trailer!


Just what I needed . Worked out well.


Bought these marker lights to go on renovation of 1961 Cree tt. Will work fine until I can locate vintage lights.....if I ever do.


Looked all over the internet for these lights .E Trailer was the only place I found that had exactly what I needed . Very happy with the service and delivery


The clearance lights were shipped quickly. They work great. Got emails keeping me informed as to order being packed, shipped, etc. Very excellent service and happy with the product. Definitely recommend using this company for products you may need.


Great replacement lights easy to install. I would buy them again.


Extremely easy website to navigate, I wish everything I ordered online was this easy. Huge selection of items as well as inventory. If you need 30 marker lights as I did or one they have it.


Excited to get them installed on camper project in next couple of months.


Worked and looked great to replace my old lights.


Perfect replacements for the origionals on my vintage camper!

Great service, received 3rd day after placing order. Product as desscribed. I used to update (make legal) an older camping trailer I am selling.


Good quality for the price. Delivery time was excellent.
Great service on the question I had. Will buy from etrailer again.


Great product. Used on a vintage Shasta travel trailer. Replaced five front ambers and five rear reds. Thanks..


I have had nothing but good results from these people and their products so far I have rebuilt two trailers with their parts and all is well with both of them
Thank you all.

Worked exactly as advertised, excellent quality for the price, which was very inexpensive. Similar products were priced at 2 to 5 times as much in local stores!


Works as described. lens has no fasteners to base but snaps on firmly.


Very quick service, good communication and very good price. No problems whatsoever, buy anything trailer related from these guys!! Thx
