Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The circuit board is sealed, which means that water will not damage the diodes or circuit board.

Video Transcript for Optronics LED Combination Tail Light Kit Installation

Today you're going to be taking a look at the Optronics LED Combination Tail Light Kit for trailers under 80 inches wide. Now it is available with just the driver's side tail light, as well as just the passenger side tail light. So here's what our trailer kit looks like once we have our lights installed. It's going to give us two combination tail lights that are going to have seven functions. Each light is going to give us our stop, turn, and tail lights, as well as a side marker, the side reflector, and a rear reflector. And then on the driver's side, we are going to have this illuminated area underneath, lighting up our license plate light.

The lights themselves are submersible, so they're going to be water proof.It's going to be great for boat trailers, or any trailers that are near a lot of water. Because inside the lens, the board is actually sealed, so it won't do any damage to the diodes inside if it does get wet. And since they do use LEDs inside, they're going to make great replacements. Because we're not going to have to worry about the bulbs to replace, and the inaudible 00:00:58 needs to break inside, they're going to be much brighter, and use less energy. In fact, each one of our lights at 12.8 volts, the stop and turn is only going to use .268 amps and the side markers are only going to use .059 amps.

The passenger side light is going to have 18 LEDs inside. And the driver's side light is going to have a total of 23 LEDs, and that's because it's going to have those extra ones for our license plate light. The license plate bracket itself is included, so that way we can make sure we have our plate on our trailers nice and legal and we can see the plate at night.Each one of our lights is going to have a polycarbonate housing as well as an acrylic lens. Now the LEDs on the inside are clear and a lens is going to be red. The lights are going to come with all the hardware necessary, and it is stainless steel, so we're not going to have to worry about it rusting or corroding and causing problems down the road.

The light itself is going to be just over six inches wide, about three and 5/8 inches tall, and two and a quarter inches deep. And it's going to be perfect for trailers that are under 80 inches wide. And our light kit is going to be DOT compliant. Our kit is going to come with a total of 25 feet of wire, and it is going to provide us with a four pole flat trailer connector, that way we can hook up to our towed vehicle.One thing I really like about the wiring harness itself is the fact that they made it so we only have to run one set of wires to each side. We're not going to have to split off our tail light signal and run it over, because we'll have our left turn tail light signal and then a right turn tail light signal here.

So now that we've seen what our lights look like and gone over some of the features, let's show you how we put them on this trailer. To begin an installation, you're either going to want to remove the wiring that's on your trailer, or if you don't have any, I would suggest starting on the front, that way we know where our connector is going to be, and then we're going to have enough room to hook everything up. So we'll start at the front tongue by our coupler, then we're going to focus on our white wire.That's going to be our ground. So we either need to find an existing hole that we can attach it to, or we can use a self tapping screw and attach it directly to the metal. So I'm going to go ahead and strip back some of my white wire. I'm actually going to use a larger ring terminal than they give you in your kit, because there is already a hole right here, and I'll put the bolt back in there, but I'll make sure to crimp on my ring terminal. Solid connection there, and we'll take the bolt and we'll reinstall it with the ring terminal underneath.Now we're going to have two sets of wires, we're going to have a yellow and brown wire, and a green and brown wire together. The yellow is going to be our left turn signal, and the green is going to be our right turn signal, and the brown is going to be our tail light signal. So we want to make sure we route the yellow wire to the back on the left side, and the green wire to the back on the right side. Now everybody's going to route theirs a little bit different, just want to make sure that they're not going to hang down below the frame, and that they are protected when we route them back towards the tail light area. So go ahead and run this and show you how we got it there.So we're over here on the driver's side of our trailer. And the way we ran our wire is we just followed along the driver's side frame rail, zip tying it and using some clips to hold the wires up out of the way. And then once we got to the back here, we just ran our passenger side wire over to the other side. So with all your wires ran, you're going to want to get your lights ready. So this is our driver's side light, since it has the yellow wire, and also if you look on the bottom, it's going to have a light for our license plate light. We look at the back side, we're going to have two channels. We're going to want to grab these carriage bolts, they'll have that little square on the head here. We're going to line it up with that channel, and we'll just slide it in place. We want to do that for both sides. Slide the bolt in, and we'll have a good secure mounting spot.Then we can take our license plate bracket, and you'll see it kind of has a little indent. And the two smaller holes will line up. Just want to make sure that indent is facing the right direction. Because if you have it like this, you may be able to get it in place but the license plate is going to be crooked and it's going to be interfering with the light. So we'll just pass it through, and depending on how you routed your wires, you can either bring them up and go through the large hole in the center, and just make sure that your wires come through and that the holes are going through the bracket like that. You want to make sure you do that for both side's lights. Now on our trailer, we already have spots opened up so we can mount our light up, so we can put our light up, but as you can see, our bracket is going to interfere with the lower section where we're mounting our light.So what we're going to do is we're going to put our light through the holes, going through the bracket, and then we'll put our bracket on the back side, that way we can still have our license plate mounting up and it'll be lit up right here. And to secure everything down, we're going to take a split lock washer, and a hex nut and make sure everything's in place. And we'll do that for both studs, and that's also how we're going to mount our other passenger side light, except we won't have to worry about the bracket. Now on the back of our light, we'll have three wires. One for our turn signal, one for our tail light signal, and one for our ground. Now it's going to be really easy, because our wire is going to be color for color. And then we'll just hook our ground wire to a good chassis ground.Now in our kit, they're going to provide us with some quick splices. However, since this is on the outside of a trailer and it is exposed to the elements, I'm not going to be using these. I'm going to change them out, and I'm going to use some heat trink butt connectors, and just trim off the excess wire and make connections directly. That way it's a little bit more solid and I have a little bit more protection against the elements. So we'll take our wire, can always estimate about how much we're going to need. And I always like to give myself a little bit of extra, that way I can just tie up the excess. But I'll cut my wire, get rid of the excess, and we'll just separate our brown and yellow wire, and grab it, pull it apart, and just take a pair of cutters and go right in the center, just be careful not to damage the rest of the wire.Strip back the end of each one of our yellow wires, take one of our butt connectors, crimp it in place. Connect the other end to our other wire. Now let's go back and we'll repeat that for our brown wire, and we can hook up our ground as well. I'm going to inaudible 00:08:32 down my connectors and make sure they have a good seal. Just want to make sure you don't burn or char the connectors if you're using inaudible 00:08:38. I'm going to take my ground wire now, and I'm actually just going to attach it directly to the frame here, using a self tapping screw.Just want to make sure that ring terminal's not going to be moving around. And with the left side hooked up, we can go ahead and do the same thing over on the passenger side. And once everything's hooked up, you can come back with a 10 millimeter socket and snug up the hardware. Then we could take some time, we'll clean up our wires, and we can put our license plate back on.Now the final step in our wiring is to make sure that all the circuits are working properly. So I hooked up my trailer, and you can see that my tail light function is working as well as the left turn signal. My brake signal and the right turn signal. All we have left to do now is hook up and hit the road. That'll finish up your look at the Optronics LED Combination Tail Light Kit for trailers under 80 inches wide.

Light fit perfectly for my boat trailer application on a shore lander trailer. Light appears to work as intended although I have not put it in the water yet to see if the lights are waterproof. This light did not come with hardware to install it. However the driver side light did. This required a trip to the local hardware store to finish the install. 451501

Just installed new lights. I think these are a nice, very bright LED light but they shipped without any mounting hardware. I would excpect that for the price it would of come with the licence plate holder and at the very least mounting screws and nuts. It added an extra hour and several more bucks to this project to hunt them down at the Home Depot. I will see in time how the lights hold up in salt water 51332

I put these on my boat trailer to replace the standard lights with LED's. They were an exact replacement and only took about 30-45 minutes to wire in and mount. I waited until dark to hook them up and test them and they look great. Much brighter than the standard bulbs and I like the fact that they are waterproof and made for a boat trailer. Hopefully we will get many years out of these lights. 264606

by:

It's a great tail multi light that fits smaller trailer fittings. I wish the company that makes this light would completely seal the red housing lens as well. It's open at the bottom to drain out water from lake submerge. If it was sealed then it would not get dirty from the inside of red lens, then it becomes less bight over time. Which is the whole reason to get the light to be brighter etc... So bad drivers can see it while they are face down on there cell phones. Every bit helps! 658444

Upon receiving my new LED boat trailer light fixtures in just 3 working days, I decided to install them the next day. My online sales rep Cathy T. nailed it when she confirmed these were the lights for my 20 ft. trailer. They had to be an exact fit, and they were, right down to the attaching bolt size and thread count. I've never wired anything before, so Etrailer really went above and beyond when they included the "Helpful Wiring Information" in our correspondence. I couldn't believe it when I discovered Etrailer provided a video on each and every light fixture they had available, including a 360 degree view of each. A friend recommended , that I try each light as I installed it, however I waited until the installation was completed before plugging the lights into my truck. I put on the Warning lights first, because I figured if they worked, everything else would also. I recall closing my eyes, before turning around and opening them to see my little Amber LED side lights lit up and my tail lights flashing. I felt like a kid on Christmas morning, as the bright LED lights did everything they were designed to do. I am 100% satisfied with Etrailer"s service and their product line. I truly believe I can count on Etrailer for all my future boat trailer needs. 603384

After spending hours trying to find replacement bulbs for my boat trailer in a tiny farming town while on a recent fishing trip, I decided to purchase LED tail lights for my EZLoader. The etrailer website was very informative and the ordering process was easy. When my new lights arrived, I installed the passenger side light first with no difficulty. After cutting the wires to length on the drivers side LED, I noticed that one side of the light had been broken in shipment. I called etrailer customer service and received top-notch treatment, kind and courteous. The replacement is on it's way and the return procedure was very easy. Great company! 569984

Ordered two lights . One drivers side , one passenger side. One of them came without mounting hardware. So off to the store I go to get some stainless hardware to put the lights on the trailer.

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. 497940

I ordered these LED Trailer tail lights (STL57RB and STL56RB) for my 1988 Shorelander trailer. I was having a hard time matching the dimensions of my worn out lights. These new lights fit perfectly. They were easy to install, but if you have questions the etrailer.com web site has resources including videos that can assist you. LED is the way to go. These lights are much brighter than the old incandescent model. 431733

I have linked some video reviews of these lights for you.

  • 6x4 Inch LED Trailer Tail Lights that Mount on Studs on 2 Inch Centers for Shorelander Boat Trailer
  • We have Wesbar lights # 271585 for the left and # 271584 for the right. They are 6 by 4 inches, LED, waterproof, mount on studs on 2 inch centers, and you would need pigtail # 40-00-003 (one for each light). LED tail light # STL56RB for the right hand side and # STL57RB for the left are a close match. They are 6-1/16 inches across and 3-5/8 inches tall. They mount on studs on 2 inch centers. The lights are submersible and the LED board sealed to keep out water.

  • Installing New LED Lights on 2011 Karavan Boat Trailer
  • It is true that a trailer ground wire will usually be white but there is never a guarantee that every trailer's wiring follows that convention. It is also indeed unusual for a ground wire to be fused; normally that fuse would be on the hot side of the circuit; but in fact having fuses in trailer wiring at all is rather unusual so it may be that the item you found (and thanks for the photo) is simply a connector used to extend the original wiring. If the original trailer lights were the...

  • Recommended Submersible Trailer Light For Karavan Boat Trailer
  • We don't have a light that is 6 x 2-1/4 x 3-1/2 inches, but we do have lights that are 6 1/16 wide x 3-5/8 tall x 2-1/4 deep if the measurements were just given in a different order. Unfortunately trailer lighting companies change their lights from time to time and the dimensions often change with a newer design. I recommend you take this opportunity to upgrade your lights on your karavan boat trailer. I recommend you use the LED Trailer Tail Light - 7 Function - Submersible - 23...

  • Do I need Left and Right Side Trailer Tail Lights or Can I use 2 Right Side Trailer Lights
  • Yes, if your trailer has a license plate directly below the left side tail light, you will need to order the Submersible LED Trailer Tail Light, # STL57RB, for the left side. This light has lighting to illuminate the license plate. For the right side you will need the light you referenced, # STL56RB. If your trailer has a separate license plate light assembly, like part # PM436B, you can use a right side light, # STL56RB, on both sides of the trailer.

  • Recommended LED Tail Light For Trailer Surface Mount With Multiple Functions
  • I can get you most of the functions you mentioned in one light, but I can't get them all. Most trailer lights do not have the reverse or backup light feature.

These lights are 7-1/2 long x 3-1/2 tall x 3-1/4 inches deep. Another option is the LED Trailer Tail Light - 7 Function - Submersible - 23 Diodes - Rectangle - Red...

  • Are there Replacement Lenses Available for the Optronics Waterproof Light # STL56RB
  • I spoke with my contact at Optronics and they do not sell replacement lenses for these lights. These lights are submersible so they are sealed from the factory. There is no way to replace the lens and re-seal it. You will need to replace the Optronics Trailer Light # STL56RB, if you need the left hand side you will need a Optronics Trailer Light # STL57RB.

  • Recommendations for Waterproof Tail Lights for a Boat Trailer
  • Optronics tail lights # ST56RS and # ST57RS are submersible assemblies. This means that water can drain out of them. What I recommend are sealed lights such as # STL57RB and # STL56RB so water cannot get in at all. Sealed lights will have far less issues than regular submersible lights.
