Item worked out perfectly 798526


Excellent product. Working very well after one year of rough service. . 568206


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 etrailer.com! 382733

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.

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! 316069


My son-in-law has been using my utility trailer a LOT - and he's been having LOTS of problems! First one of the springs snapped; we found replacements & had it back up & running the same day. Then he had a blowout; he found 2 new tires & had it back hauling the next day. Then he asked if he could install the new lights I bought from etrailer; I said yes, so he & my other son-in-law installed the new wiring & lights for me. He brought it back & I asked him to test them for me. I asked that he first turn on the parking lights, so he hopped up in the truck & turned them on. I asked him to take his foot off the brake because they were so bright, I thought I was seeing brake lights - but he jumped out & told me he wasn't pushing on the brakes! Just the parking lights alone were brighter than the old lights. When he finally did show me the stop/turn signals, I couldn't believe how bright they were! Believe me - you NEED these trailer lights! They are the best, by far! 466009

Fantastic! These are the best lights youll ever find for your trailer. I still cant believe how bright they are.

Order received a day early, excellent packing, do well buying from these folks, very knowledgeable about most any trailer issues, my go to place to buy any trailer related items. This set of LED lights is going on a very nice Chariot single motorcycle trailer I am restoring. There aren’t many things for trailers I have bought anywhere else. 902453


Very nice, very bright. 898836

Still going strong a year later. Definitely recommend! Way better than bulbs. 882010




Product as described. Clear instructions. Lights look great when lit up. Product arrived a day early. 873965


Look great 873932


Love the lights as they improve launching in the dark The rig is primarily a 18ft duck boat but is used for crabbing. The guide lights are amazing on strange ramps in the early AM. Thanks for a solid product. 876996

They worked, Nice heavy wiring unlike the cheap sets. Only drawback they still expect you to ground them through the trailer frame. Sure wish the harness came with full length ground wires. 866011

very good product, it is well worth spending a few more dollars for a good product 864688


Easy installation, have not been with them on the road. Time will tell. 857987


They worked great yes I would buy them again 857634


looks like nice parts.Thank you 857212




One of the set was defective and had to wait for a replacement delaying the project. Otherwise, very satisfied with the lights so far. Orders arrived as scheduled and installation was easy. 852636


Easy install and the lights are nice and bright, even in the daytime. I hope they last longer than the traditional bulbs that were always burning out. 845688


Simple product that works as it should. 849640

Ask the Experts about this Optronics Trailer Lights

  • Lights for a 7 Foot x 10 Foot Cargo Trailer
    It is imperative you check your local laws for lighting requirements in regards to your specific trailer, though I can tell you you no matter what you'll need stop lights, tail lights, turn signals and reflectors. There are other factors, including your trailer's GVWR that you need to take into consideration; I have added a link to a help article on trailer lighting requirements which I highly recommend checking out. That said, a 7' wide x 10' long cargo trailer is almost certain to...

  • Replacement Tail Lights for an EZ Loader Boat Trailer
    I do not know exactly what lights your boat trailer came with nor would we have an exact OEM replacement but we do have the Miro-Flex LED Trailer Tail Lights part # TLL28RK which are a submersible LED tail light that should work well for you. The lights mount via two bolts placed 2" apart on center. The circuit boards are sealed, which means that water will not damage the diodes or circuit boards. The lights do not come with sealed wiring connectors but you can add them using part #...

  • Does Miro-Flex LED Combination Trailer Tail Lights Come With Wires
    The Miro-Flex LED Combination Trailer Tail Lights # TLL28RK do not come with additional wire. The wires for these lights are 20 gauge, but you can connect them to your wiring with butt connectors such as the Deka Heat Shrink Butt Connector - 16-14 Gauge # DW05744-5. I have added a link to a video review for you to check out as well of the Miro-Flex LED Combination Trailer Tail Lights # TLL28RK.

  • Replacement Tail Lights on Malone Microsport XL Kayak Trailer
    Yes. The tail lights on the Malone Microsport trailers like the # MPG460XT are submersible. You can use the # TLL28RK to replace these lights with another submersible light or go with a completely sealed and waterproof light set with the # TLL9RK. I do recommend going with the # TLL9RK waterproof lights just because of the added protection and durability you get with this application. I've linked an installation video of these lights for you to have a look at, as well.

    You can use the Miro-Flex LED Combination Trailer Tail Lights # TLL28RK on your boat trailer from 1982 with its original wiring.

  • 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.

  • 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...

  • 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.

  • Bright LED Trailer Taillight Recommendation
    The Miro Flex LED Trailer Taillight kit part # TLL28RK is an LED that has 38 diodes which are incredibly bright. This would be a great solution for what you are looking for. I attached a picture that shows just how bright these are installed on a PWC trailer.

  • Wiring When Converting to LED Lights
    LED lights do not necessarily have three wires, they will have wires based on their function on the trailer. For example, the Miro-Flex LED # TLL28RK has three wires because they have three functions, so the white wire will be for ground, brown wire will be for tail lights, and the remaining wire will be for stop/turn lights. The Optronics # AL82AB act as clearance lights, so they have just two wires, a ground wire and lead wire. I've added a link to install videos of both lights for...

  • 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...

  • Is Surge Protection Needed When Changing From Incandescent to LED Lights?
    There is no need for any type of surge protection when making the switch to LED lights from incandescent. LED trailer lights, such as the Miro-Flex Tail Lights, # TLL28RK, are commonly being used to replace the less efficient incandescent lights. The only issue you may encounter is hyperflashing - the rapid blinking of turn signals - which is possible because LED lights only draw about one-tenth the power of incandescent lights, causing your vehicle to react as if the light has burned...

  • 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...

    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...

  • 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.

    For a waterproof LED light kit you would want to use # TLL9RK. I can verify that his kit is listed as waterproof which would include it being submersible. The # TLL28RK kit is comprised of lights not listed as submersible as you have said.

  • Replacing Trailer Tail Lights With LEDs on Older Trailer
    Thank you for that photo, it was helpful! For new LED lights you will need to replace the entire unit, and you will need to replace the entire unit. Based on the 2-1/4 inch measurement, to mount new LED tail lights you are going to have to drill new holes to install them because the standard for trailer lights today is 2 inches on center. I recommend the Miro-Flex LED Combination Trailer Tail Lights # TLL28RK which you will mount directly to your trailer frame. To attach these LED lights...

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...

  • 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...

  • Recommendations for Trailer Side Light Lens
    Without knowing which replacement lens kit you are looking at, I will give you the general rules. If it is the side of the tail light like # TLL28RK for instance, then the side lens will be red. If you mean the side of the trailer and are referring to the clearance lights, then they should be amber like # AL82AB. I've attached an article to assist.
