Miro-Flex LED Combination Trailer Tail Lights - Submersible - 38 Diodes - Driver and Passenger Side - TLL28RK

Average Customer Rating:  4.8 out of 5 stars   (1454 Customer Reviews)

5-1/4" x 5" Square. Waterproof trailer lights act as brake, tail, turn, side marker, side reflex reflector, rear reflex reflector, and license plate light. Stud mount on trailer - hardware included. 3-Wire pigtail.


I've been wanting to upgrade the trailer tails from incandescent to LED for a long time, as I felt the incandescent tails were just not visible during the daylight.

These Miro-Flex model TLL28RK are just STUPID bright, their daylight visibility is incredible, and that's just what I wanted. They were easy to mount, easy to wire, and I also like the lower power consumption.

The only thing I had to change was to drill a new hole in my light brackets for the wires, because with my old lights, the wires came out on the top, and on these, the wires exit from the bottom of the light.


One year later and these LED submersible boat trailer lights are still working like the day I installed them.

These lights have worked flawlessly on my boat trailer for years now though. Love them.
Gerald - 08/02/2022


These are a perfect upgrade on my jet ski trailer which was constantly burning bulbs maybe because the lights were not watertight. No amount of dielectric grease prevented it. These were easy to install. They are watertight and are twice as bright as the old ones. Great customer service! I highly recommend the lights and!

They are still working well and could not be happier. They are bright and a perfect upgrade. I had the marker lights go out briefly but only due to a dirty ground. Other than that, perfection! Thanks for following up! That’s ideal customer service.
Erin - 05/19/2018


Just wanted to let you know that the Optronics Miro-Flex Trailer Lights are working great!! Much brighter and more visible that the basic lights I replaced! Hope your business is doing well through this Covid crisis!! Thanks for the communication.

Still Outstanding
Michael I - 04/24/2022


Lights seem to be holding up well. Have only been installed for 6 months or so. Was blowing a bulb every other trip with the original lights which I think was due to vibration. No longer an issue with the LEDs. Would buy again.


Super fast shipping! Ordered on Saturday with etrailer's free shipping option and received my order on Tuesday. Thanks!

The lights appear to be of high quality. Comes with all necessary hardware, but I used butt connectors instead of the supplied come shaped connectors.

Lights are MUCH brighter than the halogen models they replaced; both tail and brake/turn. You could barely see the old taillights in the day time, these are far superior!


Optronics is a quality brand sold by E-Trailer which is a quality company. Parts arrived on time and in good shape. Order processing, email follow up, and tracking are second to none! Thank you E-Trailer.


They've worked great. The attachment slots could be a little stronger.


This product worked great replacing my old dry rotted, screw stripped bulb tail lights(approximately 5"x5.5") on my boat trailer. In fact, they fit in the tail light mount better than the old light. The installation couldn't have been any easier. Special thanks to Cailee V for getting me setup with these tail lights after I ordered a different tail light on my own that didnt work for my project.


These LED trailer lights are awesome. I first purchased them in 2019 for a previous trailer I sold last year. Needing a new set the only place I turned to was


Great service timely delivery and easy installation. Old out new in within an hour couldn’t ask for anything better. I normally don’t write reviews.


easy install, love the water proof sealed nature of the lights, this is my third set of lights in 18 years, and hopefully the last. whoever designed that mounting system was right on the money with it.


Appear to be good quality but honestly, I have not installed them yet.


Great product! Easy install and high quality! Would definitely purchase again!

Still looking great and working great! Very happy with quality of product and the service!

Very good quality LED trailer lights. These lights are much brighter than the conventional bulbs.

Rich - 09/27/2021


Needed to rewire my boat trailer and ordered all the necessities to do so. I upgraded to LED lights and an wishbone harness. e-trailer was the place to get everything in one stop as their selection is extensive. I can't say how pleased I am with their quick shipping and follow-up e-mails. Great products with helpful videos and notes. Thank You e-trailer! I will continue to shop with you for upcoming repairs and upgrades. No need to look anywhere else! Larry.

The Optronics Lights are working perfectly and I am very pleased with them. They are much brighter than standard lights and were a breeze to install.I have been asked about them several times and have praised your company, both for the good inventory and the extremely prompt shipping. Thank Youfor a wonderful shopping experience and no hassles. I will shop with you again.Have a wonderful day
Larry B - 07/22/2016


Easy to replace old lights with this set. This clearly solved my problem. They work superbly.


Look great, easy to install


Optronics are the best lights


Top quality


Bought these lights to replace the old, faded, cracked original lights on my flatbed trailer. They were were super easy to install. Took me 1/2 hour tops. They're easily visible even in bright sun, and they're a nice addition to my trailer.


Works great, no issues after 1 year. Get this if you are tired of burnt out halogen bulbs.

Still working, no issues!
Czarlite - 04/30/2022


Good product that's hard to find. No more grouding to trailer!

Fit perfectly, easy to install.

  • Installing LED Trailer Light with Black, Red, and Green Wires
    Typically with an LED light that has a black, red, and green wire the black wire is for ground, the red wire is for the turn/brake light circuit, and the green wire will go to the running lights circuit on the trailer. If you can tell me what model LED lights you purchased I will be happy to verify this for you.

  • Can I Use LED and Incandescent Lights on My Trailer Together
    Yes, you most certainly can use LED and incandescent lights together on a trailer. I have linked our selection of trailer lights for you to check out. If you need to choose some lights if you just let me know what dimensions you are looking for and I can make some recommendations for you.

  • Will Replacement LED Tail Lights on Boat Trailer be Compatible with Current Incandescent Lights
    There is no harm in using LED Tail Lights, like part # TLL28RK, along with incandescent lights on your boat trailer. They will work just fine together. I am linking our selection of LED tail lights for you to look through but if you can let me know the dimensions of the lights your are wanting to replace I can see if we have a similar LED option available.

  • Left Trailer Lights Keep Blowing Fuse with 2017 GMC Acadia
    There is most likely a short somewhere that is over-drawing the left trailer light circuit and causing the fuse to blow. Since the issue seems to be on the vehicle side, I recommend checking that the connector at the rear of your Acadia is clean and free of any corrosion in and around the pins where the wires attach. Inspect any wiring going back to the trailer for any pinched or damaged sections. It's also possible that the combined power draw from your trailer lights is simply too...

  • Replacement LED Tail Lights for EZLoader Trailer
    One way you can find the right tail lights for your trailer is to measure the mounting points and then measure the tail light itself. Also, take note of the shape of the lights you have, such as round, square, or rectangular. I have attached a link to the LED tail lights we offer for trailers. You can use the filters on the page to narrow down your search and find the right tail lights for your trailer. Some of the lights may not have the same dimensions but if the mounting holes are...

  • Determining What Lights are Needed on Homemade Gooseneck Trailer
    The lights you need on your newly built trailer will depend both on its size and GVWR (Gross Vehicle Weight Rating). All trailers, regardless of size, are required to have stop lights, tail lights, turn signals and reflectors. Trailers that are 80 inches wide or wider, or that are longer than 30 feet, will need additional lights and reflectors. A trailer that is 80 inches wide or wider, and has a GVWR over 10,000 pounds, will require conspicuity treatments as well. I have attached an...

  • How to Determine Correct Replacement Light for Boat Trailer
    So the SAE marking actually stands for Society of Automotive Engineers and isn't actually a part number, it just means the lens has passed their guidelines. Knowing the exact light assembly with the part number is really going to be the only way to get a replacement lens that fits, so the best option if you don't have that is to replace boat trailer's current light assemblies. To do this you will want to measure your lights as well as the spacing for mounting them in order to get the...

  • Can LED Trailer Lights be Used With Original Wiring on Older Boat Trailer
    You can use the Miro-Flex LED Combination Trailer Tail Lights # TLL28RK on your boat trailer from 1982 with its original wiring. Just make sure that the wires are in good shape and not stripped or otherwise damaged/exposed and these LEDs will work. I have added a link to a video install of the lights for you to check out.

  • Wiring Installation for Miro-Flex LED 3 Wire Trailer Lights
    The Miro-Flex LED Combination Trailer Tail Lights # TLL28RK have a separate white ground wire with ring terminal because the mounting hardware is surrounded by plastic not giving the light a solid ground connection. The ring terminal over the mounting hardware works around this to connect the light to the trailer frame. This ground wire doesn't need to be on the mounting hardware and can be attached directly to the trailer frame with a different screw or bolt if desired. The brown wire...

  • Recommended Replacement Lens for Kenway 64274 LED Light
    I was able to determine that your Kenway 64274 measures 4-7/8" x 2-7/8" and it doesn't look like we carry any lenses that will fit on that light, so the best option is to replace your taillights with something similar. I recommend using the Miro-Flex LED Combination Trailer Tail Lights # TLL28RK, which is a reliable option that will provide you with the same functionality as your Kenway light. These are simple to install LEDs that are fully waterproof, very bright with a combined 38 diodes...

  • Why Is Trailer Ground Wire Connected To Frame and Cant Vehicle Complete Circuit?
    The Miro-Flex LED Combination Trailer Tail Lights - Submersible - 38 Diodes - Driver and Passenger Side # TLL28RK has a ring terminal to ground the light to the trailer frame. If you want to ground your wiring harness at the same location instead of to the frame you can as the vehicle will ground the light. The tail lights each have a ground as well as any clearance lights. So if wiring directly to the vehicle each light will need have a jump wire for that direct wiring connection....

  • How to Determine Correct LED Tail Lights for 1999 Ranger Boat Trailer
    While there isn't a specific size of LED trailer tail lights you need for your 1999 Ranger Boat Trailer, I can tell you how to get a pair that will match. Since there generally isn't a list of parts available, to determine the correct tail lights, you simply need to measure the mounting holes from center to center and choose the lights that way.

The units are hard wired to your current trailer's lighting wiring and the units have separate ground wires. For a trailer that is smaller than 80 inches, I recommend the Optronics Micro-Flex LED Trailer Tail Lights, # TLL28RK. These light are square in shape...

  • Which LED Trailer Tail Lights are Brighter Between # TLL28RK and # TLL9RK
    Trailer tail lights # TLL28RK would be brighter than # TLL9RK but you probably would not be able to tell the difference with the naked eye. And both of them will be brighter than regular incandescent bulbs. But generally speaking the more diodes there are in an LED light the more light it produces and the brighter it will be.

  • Difference Between Trailer Lights with Wired Ground vs. Mounting Stud Ground
    The difference between your old and new boat trailer lights is likely that the old ones used their mounting hardware to make the ground connection to the trailer frame while the new ones use a wired ground. For example, lighting kit # TLL36RK uses a wired ground, the white wire with ring terminal, that connects to the trailer frame. Light kit # TL5RK on the other hand uses its two mounting studs to make the ground connection to the frame. Since I do not know which specific new lights...
