Features to know about

Brighter and More Efficient Lighting: Long-Lasting LED Design

This LED combination light kit puts an end to dim, high-draw incandescent setups. Each light uses clear LEDs behind a red lens, providing crisp illumination for stop, turn, tail, side marker, and reflector functions. The low power draw keeps things efficient—only 0.268 amps for stop and turn lights and 0.059 amps for side markers at 12.8 volts. With 23 diodes on the driver’s side and 18 on the passenger’s side, you get strong visibility without ever worrying about replacing fragile bulbs or filaments.

Built to Handle Water: Fully Submersible Housing

If your trailer ever gets backed down a ramp or runs in wet conditions, these lights are ready for it. The sealed circuit board and waterproof housing protect the internal electronics so moisture can’t damage the LEDs or corrode connections. Designed for marine use, this submersible setup stays dependable trip after trip.

All-in-One Safety Coverage: Seven Lighting Functions

Each rectangular light measures 6-1/16" wide x 3-5/8" tall x 2-1/4" deep and serves seven different functions when properly mounted—stop, turn, tail, side marker, side reflector, rear reflector, and license plate light. The driver’s side includes a built-in license plate light and corrosion-resistant bracket for a clean finish that meets DOT requirements.

Straightforward Installation: Complete Universal Kit

Everything you need is in one box. The kit includes both driver and passenger lights, stainless steel mounting hardware with 2" on-center holes, a corrosion-resistant license plate bracket, and a 25' wishbone-style wiring harness with a 4-pole connector made from 20-gauge copper wire. That long harness makes routing easy on trailers up to about 20 feet in length.

Reliable for the Long Haul: Durable Construction and Lifetime LED Warranty

The polycarbonate housing and acrylic lenses hold up to road vibration and weather exposure. Since there are no bulbs to burn out and no filaments to snap, these LEDs keep shining bright season after season. They’re backed by a lifetime warranty on the LEDs for peace of mind that lasts as long as your trailer does.

These lights do come individually with part # STL56RB for the passenger side and part # STL57RB for the drivers side.

My Karavan 12 x 6 trailer lights swap was and correct fit. The extra plate hanger and wires were not needed. I could have used 4 extra wire nuts the left side I hand twisted and Taped.
Lights had every wire they of should had.

I returned your lights and the Karavan trailer manufacturer sent me a right light for under 15.00 dollars.

Just installed these today on my fresh water only boat trailer. Replacing my old, incandescent lights with these was a snap. Time will tell how they hold up in freshwater.

E-trailer shipped the product immediately and has excellent communications.

Couldn’t be happier! Installation (removal of old bulb-type tail lights) and installed these in under 30 minutes. These lights are SO MUCH BRIGHTER!! Will definitely purchase again. Highly recommend these lights to whoever needs new trailer tail lights.

One year later and these lights have not disappointed. They’re working as well as when installed. Great product, price, shipping and an easy install. What’s not to like?



by:

Look great probally blind the guy behind me now lol .And wouldn't have to replace broken bulbs any more. I used them on a shorlander trailer



by:

etrailer delivers again. Exactly what I expected. After two hitches and several other items, etrailer has become my “go to” all my towing/trailer needs. The generous length of the wiring is appreciated as these lights will be installed so the lights and wiring can be removed & installed in just a few minutes. This trailer is used infrequently and removing the lights and wiring is the only way I can keep the squirrels from chewing the plastic!



by:

After some light disassembly, these fit perfectly under the OEM lens covers of our vintage 1976 apache ramada. LED everything now!



by:

As usual from etrailer, the product is as designed and works as it should. Shipping is slower than amzn and wmrt, but the tech support makes it worth waiting.

Thanks for picking us out of the bunch, Kevin! We'll always be here to help when you need us. Got any more projects lined up for your trailer?

Product worked perfectly. More important; I experienced the best Customer Service
in many years. It seems no Company cares about the customer. Jessica B.
was outstanding. From information, shipping to meet my needs to the follow-up
for delivery. I work for a Fortune 100 company for 32 years our customer service
had not matched this in over 15 years. Thanks for your product knowledge and
making a difference in customer satisfaction. Refreshing !! I will definetly be a returning customer and refer etrailer to my friends.

Inclusive kit which fit well



by:

So far so good. Just installed the lights which was pretty straight fwd. The included in instructions were clear and easy to follow. I did not use the supplied wire splicing nuts since I am installing this on a boat trailer. I opted for soldering and heatshrink, hoping this will withstand saltwater and corrosion better.

Lights are bright and look great. Fingers crossed that they will hold up being dunked in the ocean regularly.



by:

Lights are great quality I love the LED, the only downside is I had to buy my own hardware an connectors because the one you guys send are not good for water, if the connectors were water resistant it would be great an better hardware.



by:

Had everything I needed to complete the job



by:

Finally found led replacements that fits perfectly on my 1985 ez loader trailer!!! They were exactly what I was looking for. They are bright and look awesome!!!!!



by:

The trailer these lights are installed on is used only during waterfowl hunting going into blackish water, swamp water, ice and snow and traveling through 3 states I hunt. I'm going into my second season and all the LEDs are lite.



by:

Haven’t installed yet. I’d get plastic conduit so the wires don’t get chaffed This kit is an upgrade for a 1990 trailer



by:

This is an excellent kit which seems to be a very good quality and is quite easy to install on the trailer. This will permit me back my trailer into the water without having to unplug before getting the lights wet. Also I would advise anyone doing a trailer wiring to keep in mind that if problems arise it most likely is due to a poor ground wire connection. The only problems I had with the lighting installation was due to ground wire not having sufficient contact.



by:

Great product. I had to search a lot of different sites to find this size (roughly 6"x3.5") in a LED package because it had to fit my trailer bracket for the lights. As you can see in the picture the bracket protects two sides of the light so I needed the same size as the old ones. Thankfully eTrailer.com had the kit and it shipped within 24 hours. It bolted right on and everything I needed was included in the kit. Very happy with the product and the order process and shipping time from eTrailer. I would recommend this product to anyone.



by:

Perfect size for small trailers. Arrived fast and in perfect condition.
Also purchased (and installed) two of the the Wesbar LED Trailer Clearance or Side Marker Light w/ Reflector - 1 Diode - Black Base - Amber Lens - 47-222012. Great products.

DURABLE BRIGHT QUALITY. I've taken my trailer and these lights all around North America (California, Yukon, Texas, Key West, Newfoundland) they have never let me down.

Bought these lights for my Karavan Double Sea-Doo trailer, excellent lights, better quality than the marina and better quality than the stock ones that came with it. Ver happy with them. All wiring was perfect and durable.



by:

I’d give it 5 stars if the mounting bolts came with flat washers. Used these light as replacement light for the original lights. Mount holes were a little too big to mount without flat washers behind the nut. Great lights



by:

Installed myself for the first time on a trailer and it was all good



by:

The lights came well packaged. All parts were included in a parts bag. I have some doubts as to the quality of the wiring connectors (3M 801). The white grounding wire is too short. I ran two additional lengths of ground wire directly to the lights and eliminated any trailer body induced grounding problems. The stainless bolts were 1/4" and I thought flat washers should have been included along with the stainless lock washers. I went to the local hardware store and purchased 4 each 1/4" flat washers to complete the installation. There was more than enough wire for my small PWC trailer. Installation was straight forward. The lights look very nice and are bright even in the daylight. Worth the purchase price.

  • Recommended Replacement Tail Light Assembly for 6 inch x 3 inch Tail Lights
    It sounds like you're looking for a set of submersible tail lights, and which ones you'll want to use depends on the other type of lights you currently have on your trailer-i.e. LED or incandescent. If you've got incandescent lights already on your trailer you can use something like the Optronics # ST56RS (passenger side) and # ST57RS (driver's side) and are 6" long by 3-1/2" tall. If you've got LED lights on your trailer the LED Combination Tail Light Kit for Trailers under 80" Wide...

  • Smallest Diameter Trailer Tire with At Least 1,800 Pounds Capacity and Parts for Building a Trailer
    Assuming the trailer is as single axle and only has two tires the smallest we carry is a 205/75-14 size tire. The Kenda # AM10235 measures 26.3 inches in diameter and has a weight capacity of 2,200 pounds at 75 psi. You also want to make sure the wheel has enough capacity. If you can tell me your bolt pattern I can recommend a wheel as well.

  • Looking for Trailer Taillights that are 6 inches Wide for Boat Trailer
    Hey William, the LED Taillight kit part # TLL56RK has light assemblies that are 6-1/16 inches long and is submersible so it would work great on your boat trailer. The included hardware is stainless steel as well like you are looking for so it would work great. The mounting studs are 2 inches apart on center which is basically the standard dimensions for trailer lights. What kind of boat do you have?

  • Upgrading Pop-Up Camper Taillights to LED
    Although they are a bit smaller than the lamps you are replacing, the Optronics # TTL56RK light kit would work great for you. The lamps would provide the same tail light, turn signal and brake light functions as the lamps you are replacing. The drivers side lamp will also provide illumination for the license plate. The only spot where you might have an issue would be in how the lamp attaches to the camper. The TLL56RK lamps are bolt mounted, with the head of the bolts fitting into slots...

  • 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...

  • How to Determine Correct Tail Lights for Boat Trailer
    There is a way for you to pretty easily find out the tail lights you need, although the SAE numbers just means it has been approved by the Society of Engineers and aren't a part number, and we don't have any way of knowing specific lights for any trailer. So you will simply need to measure your current tail lights and find the one that most closely matches your measurement, and also know if your lights are surface mounted or recessed mounted. For example, the Optronics LED Combination...

  • What Does it Mean when a Trailer Light is Listed as Waterproof or Submersible
    When it comes to trailer taillights the terms waterproof and submersible are somewhat interchangeable. If a taillight is considered submersible that means that the internal circuits are waterproof and would be protected for if you were to back the trailer into water like when launching a boat. The part # TLL56RK that you referenced is listed as waterproof and submersible so it would work great on a boat trailer. Lights that aren't waterproof or submersible will still work just fine on...

  • Trailer Taillight that Has License Plate Light Availability
    Hey George, the Optronics LED Trailer Light part # STL72RB that you referenced does not have a license plate light that shines down. This installs flush in a grommet so it would not be possible for this type of light. The type of light kit we offer that has a license plate light built in would be more like the # TLL56RK which is a set for both sides of the trailer that also comes with a license plate bracket. What lights do you have on the trailer currently or is this a new build?

  • What Mounting Bracket To Use With LED Combination Tail Light TLL56RK?
    Hello Richard, thanks for reaching out. Tail lights like the LED Combination Tail Light # TLL56RK generally mount to a bracket already present on the trailer, like in the picture below. We do not carry a bracket specifically for this light, but you could use eally any piece of metal with mounting holes 2" apart on center. We do carry one bracket from CE Smith, part # CE26057AA that has mounting holes 2" apart.

    Hey Anthony, thanks for all the information. To replace the hubs, I'll need to know the part numbers off of the bearings inside and your lug nut pattern. I do not have a database that shows me what part numbers are on trailers. To replace your disc brake actuator, I recommend the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout item # DX29FR, which bolts to the top of a 3" wide coupler or the Replacement Inner Member for Dexter DX7.5L Actuator item # DX99FR if you already have a Legacy...

  • Where Is Trailer Measured To Determine What Lights Are Required
    Actually, the width of a trailer is determined by it's widest point.

If the wheels are under the trailer frame then the measurement is taken at the frame width only.

    We do have everything you need to re-wire your 6 X 12 enclosed trailer. We also have any of the lights you said you want to use as well.

These lights are virtually identical to the lights that came with the trailer so they will make a perfect replacement. They are 6-1/16" wide x 3-5/8" tall x 2-1/4" deep and come with a 25' wiring harness with a 4-way connection.

  • Can Trailer Lighting with Three Wires Replace Two Wire Setup
    Trailer taillight kits like the part # TLL56RK that have 3 wires can install on trailers that have 2 wire setups pretty easily. What you would need to do is run the white wire of this kit to the mounting hardware and you'd be set. What you have now is designed to ground through the mounting hardware so with kits like this it would be just a matter of running the ground to the same place.

You'll only need to plug this into your Jeep's harness, and getting to that is likely going to be the most difficult part as you'll have to remove some interior paneling to find it.

That makes the trailer right at 80 inches wide, but less than 30 feet long and the gross weight will be less than 10,000 pounds. If you go with the under 80 regulations, which is likely how Coleman manufactured this trailer because that is how it is set up then the trailer will need to have: Back 2...

Since you mentioned wanting a kit with wiring though we do have options like the # TLL56RK that include that as well as a pair of LED taillights.
