That's great to hear, Jim! I'm glad to hear your marker lights are working well for you. Where's your favorite boating spot? I really like Table Rock Lake in Missouri near Branson...

by:
Thought I was buying a pair wait a week to get them installed just to find out there was only one amd now have to pay shipping again to get the second one had that been clear in the beginning I would have ordered 2 and only paid shipping once and been able to get the lights amd woring on my boat trailer finished inst3ad of now paying double shipping and now waiting another week for the other light
by:
Boat trailer lights worked great
by:
The product arrived exactly on time and it was a direct replacement for the original light. Installation was a breeze so now I am ready for my fishing trip!
by:
The light works excellent. Unfortunately after I took the old one off I realized that the original was never wired up correctly from the factory lol. New light is much brighter so I might go ahead and replace the other two. Received very quickly.
by:
Had trouble tracking these specific lights down online. I have bought a few things from etrailer before and they always deliver exactly as advertised. These are a direct replacement for the lights that I had which seemed impossible to find!
by:
The lights went on easy with one positive wire and ground. Being led makes it brighter than my old lights
by:
Received a large bolt. I ordered a trailer side marker light.
by:
Ordered the LED trailer pucks. They came really quickly, and the bonus was they already had dielectric grease on the female contacts and ready to install. I was pleasantly surprised.
by:
I thought yall were just trailers , was not aware did boat as well, thanks deliver in great shape

At first the light was brighter than the other lites on the trailer. It has settled down so as to match the brightness of the other lights.

by:
I bought the led lights over a year ago and even with MI winters and all the road salt the are still working perfectly. Great product you won't go wrong buying them.

Its been a couple years of Michigan weather and winters with the most hated road salt. The LED lights are still working without any issues. I still recommend buying these lights you wont go wrong.

@Pat Road salt can be brutal on lights, so it’s great to know they’ve held up that well over a couple of years without any issues. I really appreciate you sharing that kind of long term experience since that’s exactly what people are looking for when they’re deciding. What are you using the lights on?
by:
Exact fit, fast shipping!

by:
Thank you for the fast shipping, and the light was an exact match, will use e trailer for all my trailer lighting needs.
by:
I want to thank you for all your help with my trailer you were more helpful than you realize. So this is my trailer for a 22' Flats Cat shallow draft Catamaran. I totally dismantled my trailer and buffed by hand with a wire buffer and sand blasted in some spots and applied multiple coats of some very expensive galvanize paint (Z.R.C.). I installed all new C. E. Smith Carpet (about 80'), seven new LED waterproof lights, new springs, new equalizers, new tongue jack, new wench, new safety chain, new chain brackets, all new SS hardware and a 35' long wiring harness.
I was able to send only one review with a picture of the safety chain and brackets. I'm having a little trouble with the rest..oh some of these items were bought locally or from your competitors, until I found ETRAILER. Your prices were cheaper for the exact same things. Your helpful how to videos were helpful. And Rose, your personal helpful knowledge made my buying experience very pleasant, I actually enjoyed talking to you! Thanks to ETRAILER and specifically to Rose G.

Brighter than the OEM side marker light. I was able to easily incorporate the signal circuit into the light. Now when I turn my turn indicators on, the person in my blind spot can see my intentions!

After one year the light still works without any issues. I love having a nice bright turn signal on the side of my RV.

Exact replacement
by:
Installation is super easy. Much better than the flush plugs on the other options models. Lights brightly.
Specs should include the following:
Mounting hole needs 1/4 inch minimum, and nut is 10mm.

Still lighting brightly. Mounted on boat trailer that routinely goes in seawater. No problems so far.

by:
Timely shipment of the exact items I viewed online and needed to repair my boat trailer. I will go back to etrailer when I need items in the future. Price was also fair. Thanks etrailer.

Product still works with no problem. Recommended for any use.

by:
Very bright, very easy install; only reason for 4 stars is bc I just installed them and can't speak for their longevity; I drilled a small hole in my trailer next to the main mounting hole to poke the wire through, so as not to see the wire; looked very nice.

As of the last time I launched which was in November the lights still worked great. They have been fully submersed many times in either fresh or salt water.
