1. Product - Excellent, 2. Packaging - perfect, 3. Online purchasing - seamless 4. Shipping - Terrible USPS is the worst it is slow took 5 days to cross 2 states. Vendors should not use them.

I couldn’t find anyone that had the tail light I needed for my trailer.after looking at every place I could find I finally looked on etrailer web site and found what I needed. I called and spoke with the representative to make sure it was the right one. The representative was very helpful and determined it was the right part. The part actually got delivered quite a bit faster than expected. Thank you

Looks good Marc! What kind of boat do you have?



by:

Excellent experience. Website is easy to maneuver and has a great selection. My tail light came quickly and the price was fair. I loved the follow up. I will definitely buy all of my trailer accessories from you.



by:

Plug and play LED light. Happy going fishing thanx!



by:

Firstly etrailer is excellent for service and having the parts we all need. They get five stars.
I only got this light as it was an exact replacement for the original light and where boat and trailer are so new I wanted everything to match, which they did perfectly.
I rated the light as average since the first one only lasted for 6 launches in and out. Boat and trailer have always been garaged as the picture shows and I couldn’t find an obvious reason for the failure so chalk it up to bad light.
Hope this one lasts a lot longer than the first.
If not I’ll be back to etrailer to replace both rear lights with new but different brand.



by:

Arrived early was very hassle free and easy to track my order will definitely recommend ordering from here again



by:

Super fast shipping with frequent order updates as well. The product was in perfect condition and installation was easy. I would definitely recommend this product and this retailer to a friend.



by:

Quick delivery of trailer tail light!



by:

Installed perfectly on my Tracker Pro 170 boat trailer!



by:

this was the exact replacement i needed, installation very easy, would recommend to anyone needing parts



by:

Exact replacement for my Ranger boat trailer, quick shipping!



by:

The trailer light fit perfect. Took about 3 minutes to change. My only complaint is I couldn't purchase just the lens...which is all I needed.



by:

I tried many different and cheaper tail lights over the years on my bass tracker trailer. They would all work until they didn’t. Sometimes 18 months. Sometimes 6 months. Then I switched to these (first one side and then the other). Had one for several years and the other for a little over a year. Both look great and work good as new! All sealed - no water. Well worth the extra cost.



by:

Pleased with tail light assembly, fits perfect and shipped in a reasonable amount of time. Customer service was great, in the fact that they actually follow up and make sure everything was good.



by:

Direct fit for my trailer. Arrived on time and installation took five minutes.



by:

Perfect plug & play replacement for Optronics ST-37 LH and ST-36 RH lights on a Trailstar/Nitro/Tracker trailer from 2012. No more changing bulbs or water penetration plus they are MUCH brighter.



by:

Perfect replacement; looks exactly like the original and this was only one I could find anywhere with the plug in pig tail, to where there was no splicing needed.

@Anthony Wow.. Bass pro doesn't deserve to have "bass" in their name! The tracker's are nice boats. How do you like it?


by:

The close up pictures and the measurements of the light helped me find the right one it had the exact plug as the old one it plugged right in to my pontoon trailer snd works perfect had the right mounting screws also thank you



by:

OEM replacement for a 2019 bass tracker trailer. Exact match. Worked perfectly.



by:

The cost for this light was double of one without the plug. I knew this before purchasing. It was simple to install and I didn’t have to splice wires and water proof the connections which is why I purchased this one. If you need a quick and easy install, this light worked well.



by:

I would give this product 5 stars because it looks and installed exactly like the one it replaced. The fit and function were exactly as expected. My only concern is the price. In my opinion, $65 is a very high price for a replacement trailer brake light, which significantly reduces its overall value. If it were more reasonably priced, I would have no reservations recommending it.

I own a 2024 Targa 18 WT. It sits on a TrailStar trailer. I noticed that the passenger side tail light wasn’t illuminated, just the small red side marker light. I removed the red lens and discovered they don’t have replaceable lightbulbs. The light pipes are mounted directly to the PC board as are the wires. The boat is still under warranty, but I would have had to tow my rig about 100 miles round trip to BassPro Shops for service, and I don’t know how long they would have had to keep the boat & trailer. After conducting an internet search, I saw that etrailer had the exact passenger side tail light STL0066RBG with the 3-prong pigtail connector. I saw other places selling it without the pigtail. This is an EXACT fit replacement for my TrailStar trailer. These lights are supposed to be waterproof. However, I’m old school and still in the habit of the following: {Lights are the first thing I disconnect before launching, and the last thing I reconnect before driving away}. With that said, these lights were never submerged while energized. I’ve also noticed in the reviews that it appears that it’s the passenger side light assembly that is mostly being replaced. I’m not sure if this is just a coincidence or there is a defect with the passenger side PC boards? Mine only lasted a year and a half. But anyway, it was an easy replacement. I filled the pigtail sockets with dielectric grease to keep the water out even though my boat is used exclusively in fresh water. I’ve purchased numerous items from etrailer and they always seem to have what I need. I’m a happy customer.

Glad to hear we had an exact replacement for you, Jack! Sweet boat! Being an old school kind of guy myself, I fully endorse unplugging before taking a trailer down a ramp. Keep doing that! Oh and if this every happens again, these do have a lifetime warranty on LEDs. So we have you covered! Weird that it seems to always be the passenger side though. Any more fishing trips planned for the year?

@LazerS Yes, I regularly fish the Illinois River either in the Marsailles or Starved Rock pools. I’ve also taken it to Big Cedar Lodge which is near Branson Missouri on Table Rock Lake. I’d like to take my Targa 18WT on Lake Michigan for some perch fishing.

@JackH That's awesome! We are in Wentzville, Mo, but I haven't made it down to Branson yet. Heard it is a great place to fish. I've never caught a perch either, but have eaten a few of them. Delicious! Good luck out there! : )

Exact replacement for 2025 Tracker dual axle trailer for V175. The number printed on the OG lens is S2T216AP2 which I could not find anywhere. Replacement from etrailer has same number stamped on lens. Also this one has the 3 prong plug that matches the trailer.

    Hello Michael, For the driver side you are going to want the ONE LED Trailer Tail Light - 6 Function - Submersible - 6 Diodes - Red Lens - Driver Side # STL0067RPG. The # STL0067RPG does not have the license plate holder on it, the holder should be separate on your boat trailer. The # STL0067RPG does have the license plate light on it. I included a review video where you can see that the license plate holder is separate from the light.

  • Can Broken Optronics ONE LED Tail Light Lens be Replaced
    Hey Dave, thanks for providing a photo! It looks like Optronics, for whatever reason, doesn't have a replacement lens for that trailer light so you'll have to replace the entire light assemble. you'll need part # STL0067RPG for the driver side. If you end up needing to replace the passenger side further on down the road then you'll need part # STL0066RBG for that.

  • What Causes Water To Enter a Boat Trailer Tail Light
    In regards to trailer tail lights, a common mistake that people make is not unplugging them prior to launching the trailer. The reason that this is important has to do with not only the mixing of electricity and water but also the rapid cooling. If you are using your lights down the boat ramp you'll be heating up the bulbs and housing. When the trailer is dunked under water this rapidly cooling can cause the housing to suck in water. Granted, this is more of an issue with incandescent than...

  • Does Every Trailer Taillight Need to be Grounded
    Each light will need to be grounded for it to function. That will mean that it needs to be either connected to the frame directly if it grounds through the mounting hardware or using a wire that runs to the frame if not.

If all of the light functions work then you know the issue is with the wiring on the trailer side of things.
