Features to know about

Brighter, Longer-Lasting Lighting: Efficient LED Design

Upgrading from old bulbs is a big step up in both brightness and reliability. Each light in this kit uses LEDs that last 50 times longer than incandescent bulbs and run cooler while drawing less power. At 12.8 volts, the stop and turn signal draw only 0.259 amps, and the tail light just 0.062 amps. With no brittle filaments to break, you won’t be swapping bulbs anymore—just plug in the 3-wire pigtail and go.

Ready for the Water: Fully Sealed, Submersible Construction

If your trailer ever sees rain or a boat ramp, these lights are built for it. Each circuit board is sealed inside a waterproof housing so water can’t reach the diodes or wiring. The molded plastic body and red acrylic lens hold up to repeated submersion without fogging or corrosion. That’s reliability you can trust on wet roads or when launching a boat.

All-in-One Coverage: Seven Functions and Built-In License Plate Light

Each rectangular light—8-1/16" long x 2-7/8" tall x 2-13/16" deep—handles every major rear lighting function. Together, they cover stop, tail, turn, side marker, side reflex, rear clearance, and rear reflex duties. The driver-side light adds a built-in white license plate light and includes a bracket for mounting your plate underneath. With 40 total diodes (22 on the driver’s side, 18 on the passenger’s), every signal shines bright and clear.

Simple Installation: Complete Kit with Wiring Harness and Hardware

Everything you need comes in one box—two lights, stainless steel mounting hardware, a 25-ft wiring harness, and a surface-mount design that makes replacement straightforward. The included harness simplifies running power to the back of your trailer using standard color codes: brown for tail light, green for turn/brake, and white for ground. Once mounted at the rear corners, you’re wired, sealed, and ready to roll.

Reliable Visibility: PC-Rated Beam for Wide Coverage

The PC rating means each light projects a 90-degree spread to both sides of its centerline—180 degrees total. Mounted properly at each corner, they double as rear clearance and side marker lights so your trailer stays visible from every angle. That wide beam pattern adds an extra margin of safety day or night while meeting DOT, FMVSS 108, and CMVSS 108 requirements for automotive lighting compliance.

Flatbed trailer over 80 inches wide with combination LED tail lights installed at outer corners to show proper rear clearance light placement

8-1/16" x 2-7/8" Rectangle. Waterproof lights act as brake, tail, turn, side marker, side reflex, rear clearance, rear reflex, and license plate light for trailers. Surface mount - hardware included. 3-Wire pigtail. 25' Wiring harness.

by:

If you are upgrading to LED , make sure to check you current trailer wiring. This is a 5 pin flat connector with a short piece of wire for the ground. 2 -left /2 -right... The LED lights require 3 wires...hence you have to attach the white remaining wire (short piece with an wire lug) to the trailer frame or run an additional wire for ground...



by:

Working like it’s supposed too!



by:

This kit has everything you need. If you're going through the hassle of putting new lights on, just go ahead and replace the wiring and mounting hardware too. Make sure you have it grounded correctly and get the heat shrink connectors and the trailer wiring installation kit (both sold separately). In about an hour you can have your trailer completely rewired, good as new.



by:

Great experience on etrailer + shipping, but the length of the wire assembly was incorrect. When I read 25' of wire, I expect I would have at least 25 feet from the lights to the connection on the truck. It is 25' if you connect the male and female together which then leaves you with no connection at the truck. I will either now have to splice in the wire (8 new potential break points), get a new male connector for the truck (leaving another connection point failure, or get new wire harness. I wish a longer wire kit was recommended at purchase vs. butt connectors that were too big.

BTW- The lights look great, but the wiring and the connections leave a lot to be desired.



by:

Nice bright lights! Easy to install. These units on my 2002 trailer replaced Wesbar units of almost the same size and the mounting holes were the same size and pitch. The old incandescent Wesbar lights would have been easier to replace with LED units from the same manufacturer as they had quick connection plug-ins in the harness. The new ones did not and I had to cut out the plugs from the harness and solder the wires together. I did not replace the wiring harness with the one that was supplied but will keep it for a spare for the future.
The light assemblies have openings in the back face. It would have been nice if they were completely sealed to keep out mud and water thrown up from the trailer wheels. This will require that you remove the lens from time to time to clean them. This is a problem that caused me to be pulled over by police for dim lights last year. Hopefully the brighter LED's will prevent this.
All in all, a nice product for the price though.



by:

I have not had time to install yet on my trailer but I have ordered before from etrailer and installation was straightforward and worked as they should. I will definitely order from them if needed in the future



by:

I am happy with how fast it was delivered. But the packing worried me. The small plastic lights were just tossed into the box along with the very heavy trailer hitch. The edge of the box was torn. The heavy metal hitch could have very easily crushed the plastic items. Maybe those could have been placed inside a rolled up paper bag.

But lucking out there was no breakage.

I will review after I install. But I like it. The led light wires are big enough to splice onto other wires.

Consider me happy



by:

Trailer lights are nice and bright. And still look new after a year in the sun. I would definitely buy them again and buy from etrailer again they’re great.

No problems with these lights after 2 years. Still working like new. Great lights!!



by:

fully salt water usage only. Stock lights always dieing? THIS IS THE UPGRADE you need! This light is awesome! I have it over a year now and its still as good as the day i got it, and i go fishing a lot.



by:

This kit was fantastic. It was easy to install. I made a few mods, like soldering all the wire connections, then taping them. The lights are so much better than the incandescent ones I had before. Very pleased with this kit and etrailer. Resonable price and fast shipping were the icing on the cake.

Its been a year, and I couldnt be happier with these tail lights. I highly recommend them and etrailer. Thanks again.



by:

I give the product a good rating So far. I'm not finished yet but it's coming along. The negative to me is the instructions. First is the size of printing (small and unreadable) of the combined picture of the trailer and electrical schematic (2" x 1"). It is very hard to follow and understand. Helpful tips would be a good idea. The added rear light bar I ordered needs some attention as to mounting and wiring. I think once I get through with the wiring and assembly I will be happy. All the lights and mounting technique seems well done.

Thanks for this 1 year review opportunity. My purchased was changing all my boat trailer lights to LED. They are working excellently with no problems. I think they are better than what I see on newer boat trailers. Thanks for your excellence advice, service and prompt shipping.

All LED lights continue to work perfectly. I remain very satisfied about the product and service from etrailer.



by:

Works as advertised and plenty of wire for my application



by:

Bought this kit to replace a failed set of waterproof filament type boat trailer lights. This is my second purchase of LED lights, I love how bright they are. Total cost of this complete LED set was only a few dollars more than the cost of replacing just one failed filament bulb in a sealed pod set. With six trailers at my place, I see many more LED sets in my future! As always, good price and fast shipping from etrailer.com.

Working fine, nice and bright. etrailer.com is still my go-to source for all things trailer.



by:

Received package promptly. Merchandise was in great condition and what I needed. Would purchase more accessories from this seller.



by:

Perfect for what I need! Unfortunately, delivery was by USPS and came through their new Richmond package mangling center. Long as they work, they're great. E Trailer was a one stop shop for what I needed to fix my boat trailer.



by:

The trailer lights got delivered this morning and on the waverunner trailer this afternoon. Easy to install and are a lot better than the stock lights I removed to put these on. Thumbs-up to etrailer.



by:

I needed an extra set of stop/turn lights for a bike rack. You couldn’t see the existing lights when I put a bike cover on. Problem solved. Very bright. Works and looks as described.



by:

Good lights for salt-water boat trailer. Internally, the lights and connections are potted so they look waterproof.
The wiring harness split the running light wire into two in the sealed plug, so I didn't need to expose another junction there to salt water.
Alex spent plenty of time with me checking it out that it looked good for this application, very helpful.



by:

The LEDs arrived very quickly. They were a perfect fit for the old incandescents they replaced making the installation quick and easy. Thank you!

They are still working perfectly! Great not having to worry about my trailer lights while i tow my boat

Easy install plug and play



by:

Worked great with easy install on my boat trailer. Had all parts I needed to splice wires together. I chose to use butt ends instead but the appropriate pieces were there.



by:

Everything came in fine. Although I didn't need the wire. Took about an hour to attach everything.
When I bought the jet ski, the lights on the trailer were attached with zip ties and the license plate holder was broken. It's all good now.



by:

I had to rewire my 1993 boat trailer and chose this set of LEDs to replace the older, dimmer lights/brake lights. Once I got the old stuff off, these lights went on quite quickly and with no drama. The wiring was straightforward and there was enough for my 23' trailer (18' boat) so that I didn't have to splice to add additional wiring.

I really like how bright they are, both at night and during the day. With my old setup, it was hard for others to really see my brakes or blinkers. It's not that way any more. I am much more comfortable driving in traffic knowing that others should be able to see my intentions.

  • Replacement LED Tail Lights for a Karavan Trailer
    For your Karavan trailer I recommend LED tail lights # STL57RB and # STL56RB. They are a little shorter at 6-1/16 inches but they do mount on studs spaced 2 inches apart on center. they are 3-5/8 inches tall and 2-1/4 inches deep overall. I have linked some video reviews of these lights for you.

  • LED Replacement Lights for Peterson M444
    We do have a couple of really good options for you to replace your Peterson # # PM444L and # PM444, but you do have a keen eye because the Tail Light Kit # TLL16RK will not work with the 2-1/4" spacing you have. One of the lights would interfere because it is too long overall and the back of the light cannot be rotated. Instead, for a couple of similar options that have 2" on center spacing and the needed space for you to mount them I recommend checking out the LED Combination Tail Light...

  • Gauge of Wire Used in the Waterproof, Over 80" LED Trailer Light Kit # TLL16RK
    According to Optronics the gauge of wire used in the Waterproof, Over 80" LED Trailer Light Kit with 25' Wiring Harness # TLL16RK is 20 gauge. This may seem like a very light gauge (it is), but when you consider that these lights are LEDs which draw a very small amount of amperage it is more than adequate.

    Yes. You can definitely hook up your LED tow vehicle's wiring harness with your 4-pin trailer harness that has old school taillights. If you happen to replace your boat's lights with upgraded LEDs like the # TLL16RK, you can wire those into the harness like normal. From your vehicle you inputted into the fit guide, you have a 2013 Lexus ES 350. The perfect 4-way harness you need is the Tekonsha T-One Connector # 118592.

  • Replacement Trailer Taillight Assembly Kit for 2017 Karavan Trailer
    The taillights you have installed on your trailer are not the standard style that we carry so we aren't able to determine if just the bulbs are replaceable. If you remove the lens you should be able to determine this pretty easily. The # TLL16RK that you referenced would give you all new wiring and light assemblies that have LED bulbs which basically won't ever burn out so this would be a great solution either way. Also it will bolt right up to the mounting bracket holes you have currently. I...

These lamps measure 6-1/16 x 2-5/8 inches, and would work well on your trailer. As you can see in the photo provided by one of our customers, the taillight works well on a Shoreland'r trailer.
